Is Menopausal Hair Loss Permanent?

How Hair Normally Grows and Sheds

Our hair naturally cycles through periods of growth, transition, rest, and shedding.

About 85-90% of scalp hair is actively growing at any given time. This growth phase (anagen) lasts from 2-8 years until it enters the transition phase. The transition phase (catagen) lasts for about two weeks while hair stops growing and detaches from the body’s blood supply.  After this, hair will sit dormant in the resting phase (telogen). A small percentage of scalp hair is always in the resting phase while new hair forms underneath it. Finally, the dormant hairs will shed during the last phase (exogen) of hair growth. We lose approximately 50-100 hairs every day as a normal and healthy part of the hair cycle.

Why Menopause Can Affect Hair Growth

The normal hair cycle can become less efficient during menopause. As hormone levels shift, hair follicles may spend less time actively growing new hair and more time in resting phases. This can result in increased shedding and slower replacement of lost hairs over time.

Many women first notice these changes as a wider part, less volume, or more hair showing up in the shower drain than usual. Some women also notice changes affecting their eyebrows or eyelashes during this stage of life.

Many women notice less hair shedding, and fuller-looking hair within 3-6 months of starting menopausal hormone therapy (MHT).  Hair growth takes time, though, so it's important to be patient – hair follicles follow a slow growth cycle and it can take several months of consistent hormone support before noticeable improvements appear. 

Is Menopausal Hair Loss Permanent?

Although hair changes during menopause can be alarming, generally they are not permanent. Many women experience a reduction in their hair loss when hormone fluctuations stabilize. Additionally, symptoms can also be treated directly with various therapies or by addressing contributing factors.

Hair after menopause may not return to exactly the same thickness it was earlier in life. Even so, many women find that addressing hair concerns early on helps them maintain the hair they have and support future growth.

Other Factors That Can Cause Hair Loss

Menopause is not always the only factor involved in hair thinning. Iron deficiency or thyroid disorders may result in hair changes for some women. Significant stress, illness, surgery, rapid weight loss, certain medications, and major life events may also cause temporary hair shedding.

Treatment Options for Menopausal Hair Loss

Topical Minoxidil

Topical minoxidil remains the most widely used and well-studied treatment for female pattern hair loss. It is applied directly to the scalp and improves blood flow to the hair follicles and may help to extend their growth phase. Consistent use is necessary before improvement becomes noticeable and is required to maintain results. Some women prefer topical treatment because it acts locally rather than systemically and is available without a prescription in lower doses. However some women find this treatment to be a little messy as they take time to dry and can leave a residue at the roots. 

Oral Minoxidil

Low-dose oral minoxidil has become popular recently as an alternative treatment option for topical preparations. It is often prescribed for women who have not achieved desired results with topical minoxidil therapy or who struggle with topical application. Researchers have found that oral minoxidil removes some of the potential for variable responses that can be found by applying the medication topically because it is metabolized within the body. However, because oral minoxidil is a systemic medication, treatment decisions should be individualized and discussed with a clinician.

Spironolactone

Spironolactone is an anti-androgen medication sometimes used to treat female pattern hair loss. It may help reduce the effects of androgens on susceptible hair follicles. If hair thinning has multiple causes, spironolactone may be used in combination with minoxidil if appropriate.

What to Expect When Starting Treatment

Patience is key–hair growth takes time and visible improvement often requires several months.

Some women experience increased shedding during the first few weeks of treatment. This can be frustrating, but temporary shedding is normal and is a part of the transition.  Shedding pushes the hairs that were in the resting phase out of the way to make room for new hair to take its place. This new hair will remain in the growth phase longer and will become denser and thicker before falling out in its own shedding phase.

Although temporary shedding at the beginning of treatment can be frustrating, it’s important to continue and be consistent. New growth is coming, but it takes time at first.

Emerging Areas of Research

Menopause-related changes can affect hair in several areas, including the scalp, eyebrows, and eyelashes. Researchers continue to investigate treatments that target hair follicle activity, including prostaglandin analogs such as bimatoprost, which is FDA-approved for eyelash growth. Because scalp and eyelash follicles share many of the same growth-cycle pathways, scientists are exploring whether these medications may also have applications in hair restoration. The biological link is promising, however more research is still needed to understand their role in treating scalp hair loss.

When to Talk with a Clinician

Thinning or loss of scalp hair that develops suddenly, rapidly, or in patches may indicate that evaluation is needed to identify potential underlying causes.

As we discussed earlier, hair loss is a common experience during perimenopause and menopause, but it does not mean it’s permanent. Changes in hormones, genetics, health conditions, and lifestyle factors can all influence hair density and growth.

Today, women have more treatment options than ever before, ranging from topical therapies to prescription medications and emerging areas of research. Finding the right approach often starts with understanding the underlying causes or factors.

If your hair seems to be thinning faster than you’d like, you're not alone. The menopause-trained physicians at Alloy can help uncover what’s behind the changes and guide you toward treatment options that may help you get your hair–and your confidence–back on track.
