While hormone-related hair loss is often connected to menopause, the reality is that thinning can start much earlier. Learn why hair thinning often starts during perimenopause and how hormonal changes may affect hair growth and density.
Why Hair Changes Before Menopause
Before menopause, hair can change due to fluctuating and reduced levels of estrogen and progesterone. These hormones play a crucial role in protecting hair and maintaining its growth phase. As their levels decrease, androgens (such as testosterone) start to take over, often resulting in thinner hair, reduced volume, and changes in texture.
The Hormone-Hair Connection
Hormones play a crucial role in regulating almost every vital function in our body, including hair growth and health. Various hormonal changes due to stress, menopause, and other factors can significantly affect the quality and quantity of hair.
Key Hormones That Impact Hair
- Estrogen: Often referred to as the “hair-growth” hormone, estrogen extends the growth phase (anagen) of hair, resulting in thicker, fuller strands. When estrogen drops—such as after childbirth, during perimenopause, or following menopause—hair can prematurely shift into the resting/shedding phases.
- Androgens (Testosterone & DHT): While androgens promote coarse body and facial hair, excessive levels of dihydrotestosterone (DHT) bind to hair follicles on the scalp, shrinking them and causing hair thinning or pattern baldness.
- Cortisol: Known as the primary “stress hormone,” high levels of cortisol shorten the growth phase and increase shedding.Â
- Thyroid Hormones: The thyroid controls your metabolism and cell regeneration. Both overactive and underactive thyroids (hyperthyroidism and hypothyroidism) can cause widespread hair thinning and shedding.
Common Signs of Hormonal Hair Loss
Hormonal hair loss usually occurs gradually, leading to a thinning appearance rather than sudden patches of hair loss. Signs to watch for include a widening part in the hair, thinning at the crown, or a receding hairline. This type of hair loss often comes with other symptoms such as irregular menstrual cycles, cystic acne, or unexpected body hair growth.
Treatment Options for Hair Thinning
The HRT ReBalance program and The Activator Hair Restoration are comprehensive, clinically-driven treatment options designed to address thinning hair. Both services tackle hair loss from multiple angles, ranging from internal hormonal balance to localized scalp and follicle stimulation.
The HRT ReBalance program
A form of hormone replacement therapy, the ReBalance method uses pellets with biodentical testosterone or estrogen — identical to what your body naturally produces. Made of yams, the pellets are vegan, natural, safe, and more effective than some pellets on the market.
The Activatorâ„¢ is a non-surgical treatment that combines microneedling exosomes (or growth factors) and an at-home regimen to slow or reverse hair loss naturally and encourage thicker, denser hair.
Frequently Asked Questions
Can perimenopause cause hair loss?
Absolutely, perimenopause can lead to hair loss for many women. As estrogen and progesterone levels decrease, the hair growth phase gets shorter, and the rise in androgens can cause hair follicles to shrink. This typically results in a wider part, more hair shedding, and hair that feels finer overall.
Is thinning hair hormonal?
Thinning hair is often linked to hormonal changes. Hormones such as androgens (like DHT), estrogen, and thyroid hormones play a key role in managing your hair growth cycle. When these hormone levels shift or become unbalanced, it can throw off the hair growth process, leading to smaller follicles and increased hair loss or thinning.
Does low estrogen affect hair growth?
Low estrogen levels can really impact hair growth. Estrogen plays a key role in keeping hair in its active growth phase. When estrogen drops—whether from perimenopause, menopause, childbirth, or changes in medication—hair tends to spend less time growing and more time in the resting and shedding stages.
Can HRT help hair loss?
Hormone Replacement Therapy (HRT) can be beneficial for hair loss, especially when it’s linked to hormonal imbalances like those experienced during menopause. By boosting estrogen levels, HRT can extend the hair growth phase and minimize shedding, but keep in mind that the outcomes can differ significantly from person to person.
