Hello, staying up late, stressful, spicy and greasy foods may all lead to an increase in hair loss, but in fact this is only an inducement for hair loss, and the root cause is androgens such as dihydrotestosterone in the body. Dihydro testosterone is produced by testosterone under the action of 5α reductase, and female adrenaline also secretes a small amount of androgen, so some women will also have androgenetic alopecia.

Finasteride inhibits androgen, so it will also have an effect on female hair loss. Low concentration is recommended for women.
