How Aging Changes Your Hair
In order to address the challenges presented by Hair loss, we first need to know how much of the damage caused by aging is reversible. According to rogers and avram (2008), virtually all the damage related to Hair loss due to aging is reversible. As such, scientists today provide us with far more options for reversing the damage than previously existed.
Our guide uses science-based recommendations from leading medical authorities to provide you with easy-to-follow advice on how to fight back against Hair loss due to aging.
What Happens Beneath Your Scalp as You Age
As we age, our scalps undergo several biological changes. One of the most critical changes that take place involves Hair Follicles. Approximately 90% of the 100,000+ Hair Follicles present on the human scalp are actively growing at any time (almohanna et al., 2019). However, as we age, the percentage of Hair Follicles in the active growing phase (anagen) decreases. The number of Follicles in the resting (telogen) phase increases. The end result is fewer and thinner hairs.
Key Biological Changes in Men’s Hair with Age
Androgenetic alopecia (male pattern baldness) — as stated earlier, this is the most common type of Hair loss in men. Androgenetic alopecia is dependent upon hormones. Specifically, when Testosterone circulates through the bloodstream it is converted into dihydrotestosterone (DHT) via an enzyme called 5-alpha-reductase (5-AR). DHT binds to receptors located within the Hair follicle. Over time this binding causes the follicle to shrink until eventually it stops producing Hair. Hair loss associated with androgenetic alopecia usually starts at the front edge of the scalp near the forehead and progresses backward towards the crown.
Gray Hair — as we age, we naturally produce fewer melanin-producing cells (melanocytes) within our Hair Follicles. Without sufficient melanin, our Hair loses its pigment and turns gray. Gray Hair grows more slowly than younger colored Hair, and tends to be thicker, coarser and drier. Consequently, we need to treat it differently than we did when we were younger.
Decreases in natural oil production — our scalps produce less Sebum as we age. While this decrease in Sebum may reduce dandruff and flaking of the scalp, it can lead to dryness and brittleness in the Hair. Additionally, as we age, our Hair has a decreased ability to retain moisture. Thus, it is extremely important to keep our Hair properly moisturized as we age.
1. Choose the Right Shampoo for Aging Hair
When selecting a shampoo for your aging Hair, consider a product that is designed for dry or normal Hair rather than oily Hair. Most Shampoos contain detergents that strip away natural oils from the Hair. This can lead to dryness and breakage in older men. Laureth sulfate is a cleaner that is considered gentle on Hair. Consider products containing laureth sulfate as opposed to lauryl sulfate. Avoid using shampoo every day unless you have a mild formula. Typically, older men will find success using shampoo every two to three days. Make sure that your shampoo has a ph level that matches your Hair and scalp. Ideally, your shampoo should have a ph level below 5.5 since that is closer to the ph level of your scalp. Products with a higher ph level can swell up your Hair shaft making it more brittle and prone to breaking. Look for Shampoos labeled “ph balanced” or that contain ingredients such as citric acid or glycolic acid. Medicated Shampoos are available that can help control conditions such as seborrheic dermatitis (dandruff). Ingredients such as zinc pyrithione, ketoconazole and selenium sulfide are useful for treating scaly conditions of the scalp.
2. Never Skip Conditioner
Most men ignore conditioner because they believe they don’t need it. Nothing could be further from the truth! Conditioners are absolutely necessary as you age.
Conditioners work by depositing positive ions onto negatively charged ion sites along the shaft of your Hair. These deposits flatten out the layers of overlapping cuticles along your Hair shaft causing less friction between hairs and allowing for better reflectivity of light which creates improved shine and luster (d’souza & rathi, 2015). Also, as you age, your Hair becomes more brittle and prone to breakage. Conditioners fill gaps in damaged areas of your Hair shaft providing additional strength and helping prevent breakage.
How to Use Conditioner Properly
- Always apply an instant conditioner immediately after each shampoo and let sit for 3 – 5 minutes before rinsing off.
- Deep condition at least once per week using a leave-in conditioner for 15 – 30 minutes depending on how severely damaged your Hair is.
- For fine thinning hair, try using a thickening conditioner to temporarily add bulk.
- Try Silicone-based conditioners such as dimethicone or amodimethicone if you’re looking for extra shine on your gray or white Hair.
3. Address Male Pattern Baldness Early
If you’ve noticed your Hair line receding or you’re experiencing thinning patches on the crown of your head you’re likely suffering from androgenetic alopecia (male pattern baldness). This is the most common form of Hair loss in men and it’s hormone-related — specifically DHT (not hat wearing or frequent shampooing). For styling strategies to work with a receding hairline, see our expert guide.
According to The Mayo Clinic, male pattern baldness usually develops gradually and in a specific manner — first starting with a receding hairline then progressing upward toward the crown (mayo clinic, 2020). The condition is progressive and will continue to cause follicular miniaturization until you seek treatment.
Fortunately there are proven medical treatments available to combat male pattern baldness.
Minoxidil (Rogaine)
Available over-the-counter in liquid, foam and shampoo forms, rogaine contains minoxidil which is placed on the scalp twice daily for men. Clinical evidence indicates that rogaine stimulates many men to regrow lost Hair or slow down Hair loss (mayo clinic, 2020). Minoxidil takes six months or longer to begin working — and continued use is required otherwise any gains will disappear.
Side effects are mild and infrequent (scalp irritation and occasional excessive growth of facial Hair).
Finasteride (Propecia)
Prescription oral medication Propecia contains finasteride which acts by blocking the conversion of Testosterone into dihydrotestosterone (DHT) by inhibiting type ii 5-alpha reductase. Many men using Propecia report slowing down their Hair loss and/or experiencing new growth (mayo clinic, 2020). Clinical trials indicate that finasteride may be slightly less effective in men aged sixty-one years old or above. Rare potential side effects of finasteride include reduced sex drive and/or sexual function; however these symptoms usually disappear once treatment ends.
Dutasteride
More recently developed was dutasteride — a dual 5-alpha reductase blocker which inhibits both type-i and type-ii 5-AR. Head-to-head clinical trials comparing dutasteride vs. Finasteride showed dutasteride produced significantly more increased total Hair counts (mean difference = 28.57; CI: 18.75–38.39; p<0.00001); moreover rates of sexual adverse events did not differ significantly between dutasteride and finasteride in either trial (Zhou et al., 2019). Consult with your dermatologist regarding whether dutasteride is right for you.
Surgical Options for Advanced Hair Loss
Men with severe Hair loss who desire a more permanent solution may opt for surgical intervention such as transplants whereby a surgeon relocates individual hairs from an existing source (such as the sides/back of the head) into balding regions. Surgical procedures require no hospital stay but may require repeated visits to achieve desired outcomes. Keep in mind that even after transplantation, new Hair loss may develop in untransplanted Follicles over time.
Low Level Laser Therapy (LLLT)
The u.s. FDA has cleared lllt as safe for the treatment of genetic Hair loss in men. Some preliminary studies suggest improvements in total Hair density with lllt; nevertheless more research is required in order to confirm long-term effectiveness of this modality.
4. Fuel Your Hair: Essential Nutrients for Growth
While most people associate Nutrition with muscle growth or weight management — Nutrition also impacts our scalp health. In fact, researchers tell us that our scalp tissues are among the most metabolically active in our bodies — thus they require regular nutrient replenishment in order to remain healthy (Guo & Katta, 2017).
A comprehensive article entitled “nutritional deficiencies presenting with Hair loss,” written by baylor college of medicine’s Emily L. Guo and dr. Rajani Katta Department of Dermatology, Houston Methodist Hospital appeared in july of 2017 in Dermatology Practical & Conceptual. After reviewing numerous scientific articles, they concluded that there exists a multitude of nutritional deficiencies capable of contributing to hair loss (Hair loss).
Iron
Iron deficiency represents the most widespread nutritional disorder affecting humans globally. Moreover, numerous scientific studies have documented iron deficiency as a cause of generalized thinning of the Hair (almohanna et al., 2019; Guo & Katta, 2017). Premenopausal women are at greatest risk due to menstrual bleeding; however, older men are not immune — especially when considering gastrointestinal blood loss as a major risk factor. Both iron deficiency states affect DNA synthesis in rapidly dividing cells — such as those present throughout the matrix of the Hair follicle.
Zinc
Zinc serves a crucial role as a cofactor for thousands of enzymes/and transcription factors involved in cellular metabolism/and proliferation processes. Studies conducted on patients afflicted with various types of alopecia demonstrate that all groups tested exhibited significantly lower levels of serum zinc compared to individuals without alopecia (kil et al., 2013; Guo & Katta, 2017). Foods rich in zinc include meats/shellfish/legumes.
Vitamin D
Animal models have demonstrated vitamin d’s direct influence on the cycling/Hair follicle activity — additionally, expression of vitamin d receptors is observed in the outer root sheath layer of actively growing Hair Follicles during anagen (Guo & Katta, 2017). Potential risk factors for vitamin d deficiency among older men include reduced sunlight exposure/obesity/darker skin tone — discuss with your healthcare provider about obtaining a vitamin d test.
Biotin (Vitamin B7)
While there is considerable marketing promoting Biotin as beneficial for enhancing/maintaining healthy-looking locks — Biotin supplementation only provides benefit to those individuals demonstrating Biotin deficiency. In reality — Biotin deficiency is relatively rare — and the FDA has issued warnings that excessive amounts of Biotin taken as supplements can adversely impact certain lab tests — do not supplement with Biotin without confirming deficiency.
Protein
Protein malnutrition represents an absolute direct causative agent for thinning/shedding of the Hair. keratin/fibrous structural Protein constitutes approximately 85% of human Hair — adequate intake of Protein-rich foods are essential/necessary for maintaining healthy Hair.
Important Warning: Don’t Assume More Is Better
Over-supplementing with vitamins a/e/selenium can lead to an unintended consequence — Hair loss (Guo & Katta, 2017). Supplements are not regulated by the FDA — therefore always consult your physician prior to initiating any supplement regimen aimed at improving your Hair growth.
5. Practice Scalp-First Thinking
Many men focus on their hair strands and completely neglect the foundation those strands grow from — the scalp.
Scalp health is directly linked to hair density and quality. A compromised scalp environment — whether from inflammation, excess oil buildup, or untreated dermatitis — impairs follicle function. Research published in the Journal of Investigative Dermatology found that oxidative stress in dermal papilla cells of men with androgenetic alopecia may play a significant role in the balding phenotype (Upton et al., 2015, as cited in Guo & Katta, 2017).
Scalp care basics:
- Massage your scalp regularly. Gentle scalp massage improves blood circulation to the follicles, which supports nutrient and oxygen delivery. Use your fingertips (not nails) in small circular motions for 3–5 minutes.
- Address dandruff aggressively. Seborrheic dermatitis causes inflammation around the follicles. Vitamin E deficiency has been noted in patients with seborrheic dermatitis, and a possible relationship between vitamin D and scalp psoriasis has been documented (Almohanna et al., 2019).
- Protect your scalp from UV exposure. The Mayo Clinic recommends protecting hair from sunlight and other sources of ultraviolet light, particularly for men with thinning hair who have more scalp exposed to the sun (Mayo Clinic, 2020).
- Avoid harsh chemical treatments. Hot oil treatments, permanents, and excessive heat styling can cause scarring of follicles — leading to potentially permanent hair loss (Mayo Clinic, 2020).
6. Style Smarter, Not Harder
As hair thins with age, the instinct is often to over-style — but certain styling habits actually accelerate hair loss. For inspiration on cuts that work with aging hair, explore our guide to hairstyles for older men.
The Mayo Clinic specifically warns against hairstyles that pull hair tight, such as cornrows or tight ponytails, as these can cause traction alopecia — a form of hair loss caused by chronic tension on the follicle (Mayo Clinic, 2020). The same applies to rubber bands and tight braids.
Smart styling principles for older men:
- Use a wide-tooth comb, especially on wet hair. Wet hair is significantly more fragile and prone to breakage. Detangle gently, starting from the tips and working your way up (Mayo Clinic, 2020).
- Avoid excessive heat. Hot rollers, blow dryers on high heat, and flat irons damage the cuticle and lead to split ends and breakage. When blow-drying, use the lowest effective heat setting and keep the dryer moving.
- Work with volume, not against thinning. The Mayo Clinic advises using styling products that add volume and choosing hairstyles that make thinning less noticeable (Mayo Clinic, 2020). Shorter haircuts tend to make thinning less apparent and are generally easier to style.
- Consider hairpieces or color strategically. Coloring hair slightly darker can reduce the visible contrast between hair and scalp, making thinning look less pronounced. A professional stylist experienced with mature men’s hair can be invaluable here.
7. Lifestyle Factors That Quietly Damage Your Hair
Some of the most significant contributors to hair loss in older men have nothing to do with products or styling — they’re lifestyle habits.
Smoking: The Mayo Clinic notes that some studies show an association between smoking and baldness in men (Mayo Clinic, 2020). The mechanism is thought to involve reduced blood flow to the scalp and oxidative damage to hair follicle DNA.
Chronic Stress: A very stressful event can trigger telogen effluvium — a condition where large numbers of follicles prematurely enter the resting (telogen) phase, resulting in diffuse shedding several months after the triggering event (Mayo Clinic, 2020). This is typically temporary, but in older men with already reduced hair density, the impact is more noticeable.
Poor Nutrition: As outlined in Section 4, caloric restriction and protein malnutrition directly impair hair growth. The matrix cells in the follicle bulb have very high turnover rates, and “a caloric deficiency or deprivation of essential nutrients can quickly disrupt the hair cycle” (Almohanna et al., 2019, p. 18).
Medications: Several common medications prescribed to older men — including some for high blood pressure, arthritis, depression, heart conditions, and gout — list hair loss as a side effect (Mayo Clinic, 2020). Talk to your doctor about whether any of your current medications could be contributing to hair changes.
Medical Conditions: Diabetes, lupus, and thyroid disorders can all cause or worsen hair loss. If your hair loss is sudden, patchy, or accompanied by other symptoms, seek medical evaluation (Mayo Clinic, 2020).
8. Don’t Neglect Beard Care
For many older men, a well-groomed beard becomes an important part of personal style — and beard hair requires its own care regimen.
Beard hair tends to be coarser and more prone to dryness than scalp hair. As you age, beard growth can become patchier and the skin underneath more sensitive.
Key beard care tips:
- Wash your beard 2–3 times per week with a dedicated beard wash or a gentle, sulfate-free cleanser. Avoid using regular body soap, which is typically too alkaline and will dry out the skin underneath. Learn how to prevent beard rash with the right washing technique.
- Apply beard oil daily. Natural oils like jojoba, argan, and sweet almond oil closely mimic sebum and help moisturize both the beard hair and the skin beneath. This reduces itchiness, flaking, and brittle beard hair.
- Trim regularly. Even if you’re growing a longer beard, regular trimming removes split ends and keeps the beard looking intentional and groomed. Electric trimmers with adjustable guards offer precision without the irritation of blades for sensitive skin.
- Brush with a boar bristle brush. This helps distribute oils evenly through the beard, train the growth direction, and stimulate circulation in the underlying skin.
- Watch for skin conditions. Seborrheic dermatitis can affect beard skin just as it does the scalp. If you notice flaking, redness, or persistent itch under your beard, a medicated wash containing ketoconazole may help, or consult your dermatologist. Avoid common beard grooming mistakes that worsen skin irritation.
9. When to See a Dermatologist
Not all hair changes are a normal part of aging, and some require professional evaluation. The AAD recommends seeing a board-certified dermatologist if you experience:
- Sudden or patchy hair loss, particularly round or oval bald patches that appear rapidly. This may indicate alopecia areata, an autoimmune condition where the immune system attacks hair follicles (AAD, 2023).
- Hair loss accompanied by scalp pain, itching, or visible skin changes — including redness, scaling, or oozing.
- Persistent hair shedding that exceeds what’s typical (more than 100 hairs per day on a consistent basis).
- Diffuse thinning across the entire scalp rather than a predictable male-pattern progression, as this can signal an underlying medical condition requiring investigation.
A dermatologist may conduct blood tests to check for iron levels, thyroid function, zinc, vitamin D, and other potential contributors to hair loss. A scalp biopsy or trichoscopy (scalp light microscopy) may also be used to assess follicle health more precisely (Mayo Clinic, 2020).
The Takeaway
Aging gracefully doesn’t mean accepting every negative hair change without a fight. Whether your concern is thinning, dryness, a receding hairline, or scalp health, science gives older men more tools than ever before.
The foundation is straightforward: choose the right shampoo and conditioner for maturing hair, get a handle on nutrition and lifestyle factors, consult your doctor about evidence-based medical treatments if needed, and stay consistent. Hair doesn’t respond to overnight fixes — but it does respond to sustained, intelligent care.
Start with one or two changes from this guide, give them at least three to six months to show results, and build from there. Your hair — and your confidence — will thank you.
