Can Perimenopause Cause Hair Changes?

Yes, Perimenopause can absolutely cause noticeable changes to your hair. During this phase of life, your body experiences significant fluctuations in estrogen and progesterone—hormones that play an important role in hair health. Understanding what’s happening and why can help you feel more prepared and empowered to care for yourself during this transition.

How Hormonal Changes Affect Your Hair

The Hair-Growth Cycle

Hair grows in phases: the active growth phase (anagen), the transition phase (catagen), and the resting and shedding phase (telogen). Estrogen and progesterone help keep hair in the growth phase longer and support the overall health of hair follicles. When these hormones become irregular during perimenopause, more hair follicles may move into the shedding phase at once—a condition called telogen effluvium. This can feel like you’re losing more hair than usual, even though you’re not necessarily losing it faster overall.

Increased Shedding

You might notice more hair in your brush, on your pillow, or in the shower drain. This temporary increase in shedding is one of the most common hair-related changes during perimenopause. While unsettling, it often improves as hormone levels stabilize.

Hair Thinning

Falling estrogen levels can cause hair strands to become thinner and finer over time. You may notice your hair has less volume or feels less full, particularly around the scalp. This is especially common on the crown and top of the head.

Changes in Texture

Some people find their hair becomes drier, curlier, straighter, or coarser than it used to be. Hair texture changes happen because hormones affect the sebaceous glands and oil production in the scalp. Your hair’s moisture balance and natural curl or straightness can all shift as estrogen and progesterone fluctuate.

Scalp Dryness and Sensitivity

Declining estrogen can reduce oil production on your scalp, leading to dryness, itching, and sensitivity. Some people experience flaking or redness. On the flip side, others may develop an oily scalp if their sebaceous glands become overactive.

Unwanted Facial Hair

As estrogen decreases, the relative effect of androgens (male-pattern hormones) becomes more pronounced. This can lead to increased facial hair, particularly on the chin and upper lip. While this doesn’t happen to everyone, it’s a recognized and frustrating side effect for many people in perimenopause.

Other Possible Causes to Consider

While perimenopause is a common culprit, hair changes can also result from other factors. It’s worth exploring these possibilities so you can address the true underlying cause:

• Thyroid disorders – An underactive thyroid (hypothyroidism) can cause hair loss, thinning, and dryness.
• Nutritional deficiencies – Low iron, zinc, vitamin D, and B vitamins are linked to hair loss and poor hair health.
• Stress – Chronic stress can push hair into the shedding phase and impact overall scalp health.
• Sleep deprivation – Poor sleep affects hormone regulation and reduces your body’s ability to repair and regenerate hair.
• Medication side effects – Some medications, including certain antidepressants and blood pressure drugs, can affect hair health.
• Autoimmune conditions – Alopecia areata and other autoimmune disorders can cause sudden or patchy hair loss.
• Hair care practices – Tight hairstyles, excessive heat, harsh treatments, or overwashing can damage hair and cause breakage or loss.
• Scalp conditions – Psoriasis, seborrheic dermatitis, or fungal infections can cause itching, flaking, and hair loss.

Practical Hair-Care Tips During Perimenopause

While you navigate hormonal changes, these hair-care practices can help support your hair health and minimize damage:

• Use a gentle shampoo and conditioner. Choose sulfate-free, pH-balanced products designed for your hair type (dry, oily, combination, or sensitive scalp).
• Wash your hair less frequently. If possible, space out washes to every other day or 2–3 times per week to reduce scalp stress and preserve natural oils.
• Minimize heat styling. Let your hair air dry when possible. If you must use heat, use a lower temperature setting and always apply a heat-protectant product first.
• Avoid tight hairstyles. Styles like tight ponytails, buns, and braids can cause traction alopecia (hair loss from tension). Choose loose, relaxed styles instead.
• Be gentle when brushing. Use a wide-tooth comb or soft brush, especially when your hair is wet. Start at the ends and work your way up to avoid breakage.
• Deep condition regularly. Use a hydrating hair mask or deep-conditioning treatment once or twice a week to combat dryness and improve texture.
• Moisturize your scalp. Apply a light scalp oil or leave-in scalp treatment if you’re experiencing dryness and irritation.
• Trim your hair regularly. Getting a trim every 6–8 weeks helps prevent split ends and keeps your hair looking fuller and healthier.
• Protect your hair at night. Use a silk or satin pillowcase to reduce friction and breakage while you sleep.
• Stay hydrated. Drink plenty of water throughout the day. Proper hydration supports healthy hair from the inside out.

Nutrition and Supplements for Hair Health

What you eat matters for your hair. During perimenopause, pay special attention to nutrients that support hair growth and overall hormone health:

• Iron-rich foods – Red meat, poultry, legumes, dark leafy greens, and fortified grains help prevent anemia-related hair loss.
• Protein – Hair is made of protein (keratin), so adequate intake is essential. Include chicken, fish, eggs, beans, tofu, and nuts.
• Omega-3 fatty acids – Found in fatty fish (salmon, sardines), flaxseeds, chia seeds, and walnuts, these support scalp health and reduce inflammation.
• Zinc – Oysters, beef, pumpkin seeds, and legumes contain zinc, which supports hair follicle health and repair.
• Vitamin D – Fatty fish, egg yolks, fortified milk, and sunlight exposure help with vitamin D levels, which plays a role in hair growth.
• B vitamins – Whole grains, eggs, meat, and leafy greens provide B vitamins needed for energy and protein metabolism.
• Biotin – Eggs, almonds, salmon, and sweet potatoes contain biotin, a B vitamin often promoted for hair and nail health.

If you’re concerned that your diet isn’t providing enough of these nutrients, talk with your healthcare provider before starting any supplements. A blood test can identify specific deficiencies that need addressing.

When to Contact a Healthcare Professional

Hair changes during perimenopause are usually temporary and manageable, but certain situations warrant a conversation with your doctor or a dermatologist:

• Hair loss is severe, sudden, or accompanied by scalp pain or burning.
• You develop patchy or circular areas of hair loss (which could indicate alopecia areata).
• Hair loss persists for more than 6 months despite changes to your hair-care routine and diet.
• You experience scalp redness, swelling, warmth, or signs of infection.
• Hair loss is accompanied by other symptoms such as unexplained fatigue, weight changes, or temperature sensitivity (these might indicate thyroid issues).
• You’re unsure whether your hair changes are related to perimenopause or something else.

Urgent Warning Signs

Seek immediate medical attention if you experience any of the following:

• Sudden, widespread hair loss affecting your entire scalp or body.
• Hair loss accompanied by fever, chills, or signs of scalp infection (pus, severe redness, warmth).
• Hair loss associated with severe itching that prevents you from functioning normally or causes open wounds.
• Hair loss combined with other concerning symptoms such as chest pain, difficulty breathing, or severe dizziness.

A Final Word

Hair changes during perimenopause can feel frustrating and personal, but remember that you’re not alone—these changes are incredibly common and usually temporary. By understanding what’s happening to your body, taking steps to care for your hair and scalp, nourishing yourself well, and seeking professional guidance when needed, you can navigate this transition with confidence. Be patient and kind to yourself; your hair will often improve as your body adjusts to this new phase of life.
