How to treat my hair loss?

Thanks for asking. All birth control pills have the ability to influence the growth and appearance of your scalp and body hair. While birth control pills may not affect your scalp hair at all, they can do so if you have a genetic predisposition to hormonal hair loss and/or follicle sensitivity to androgens (male hormones).
In these cases, the effect they have on your hair can either be positive or negative and this depends on the pill’s hormone combination and/or on your body’s metabolism. Interestingly enough, certain birth control pills are sometimes prescribed solely to combat hair loss as a hair loss treatment – such as Dainette in the case of hair loss associated with PCOS.
It’s important to note that androgens are present in all women, but in smaller amounts than men. However, some women’s hair follicles are sensitive to even normal or sub-normal amounts of male hormones, while others only experience hair loss when they have excess amounts – if at all. Examples of anti-androgenic contraceptive pills are Yasmin, Dianette and Cileste.
There are certain treatment options for hair loss, which include PRP or Excimer laser which can be tried to stimulate hair growth. All the best. It would be best to see a dermatologist. All the best.
