Estrogen and progesterone levels fall, meaning that the effects of the androgens, male hormones, are increased. During and after menopause, hair might become finer (thinner) because hair follicles shrink. Hair grows more slowly and falls out more easily in these cases.
As with male pattern baldness, female pattern baldness comes from hormone imbalances, specifically dihydrotestosterone imbalances, or DHT. This hormone is similar in structure to testosterone, but it is significantly more potent [3]. DHT can attach to receptors on the hair follicles, causing the follicles to shrink.
Although most people think of estrogen or testosterone when they think of a hormone imbalance, issues with your thyroid can also lead to hair thinning. Once your hormonal imbalance is corrected, your hair should begin to grow again -- plus you'll probably feel more energetic and better overall.
According to Harvard Health Publishing, topical minoxidil is the most common treatment for androgenic alopecia or hormonal hair loss as opposed to corticosteroids for non-hormonal hair loss treatment. Corticosteroids reduce inflammation and lower the immune response in alopecia areata.
Androgens—such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)—are the key factors in terminal hair growth.
Lifestyle changes, such as a healthier diet, exercise, and stress reduction will also help you get your hormone levels back on track. Once equilibrium is restored to your hormones, hair loss associated with your hormone issue should slow or cease, and in many cases, hair that was loss may be replaced by new growth.
Low progesterone and estrogen are also often to blame for thinning hair during menopause. Hair loss from menopausal hormone deficiencies can take many forms. Most women notice thinning throughout their scalps, which may be visible when you part your hair or you might notice a thinner pony tail.
Many people want to know if hormonal hair loss can be reversed. The answer is yes! Fortunately, unlike genetic hair loss, most hair loss caused by hormonal imbalances is reversible.
Menopausal women may have another treatment option for their hair loss: hormone replacement therapy. Although controversial, these hormones — available in estrogen and progesterone creams, pills, and patches — can help prevent hair loss as well as ease menopause symptoms.
Estrogen Excess
Just like excess testosterone and excess DHT can cause hair troubles, so can too much estrogen. For some women, excess estrogen may trigger hair loss because of a gene variant that affects the functioning of an enzyme (aromatase) that processes estrogen.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Hair loss can also be triggered by hormone changes that occur during menopause. During menopause women's estrogen and progesterone levels drop causing hair to grow more slowly and become thinner.
Here's the hard truth: Little can be done to permanently change the diameter of individual hair strands. Thickening products can do wonders to temporarily plump hair strands, but when it comes down to it, fine hair is genetic and can't be changed.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
With telogen effluvium, it is common for hair to grow back within 3 to 6 months after the cause has been dealt with. Sometimes, the rate of shedding slows down but does not stop entirely. In most cases, no more than 50 percent of the hair is lost.
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
How much B12 should I take daily for hair growth? The lowest amount recommended that should be traceable in your body is 2.4 mcg. While you are looking for a difference in your hair growth you can increase this dosage to 3 mcg and beyond.
Lower estrogen and progesterone levels: Estrogen and progesterone stimulate hair growth, which is why pregnant women—who are producing extra levels of these hormones—tend to experience thickening hair during their pregnancy.
Excess thyroid, estrogen, progesterone and DHEA supplements can all cause hair loss. When the hair follicle is exposed to higher-than-normal levels of hormone, it shuts down and stops responding.
How are hormonal imbalances diagnosed? Healthcare providers typically order blood tests to check hormone levels since your endocrine glands release hormones directly into your bloodstream.
While biotin is added to some shampoos that claim to reduce hair loss, there is no evidence that this works. Consuming foods rich in healthy vitamins and minerals will help with overall hair health. The best natural sources of biotin are meat, eggs, fish, seeds, nuts, and vegetables.
