hi im a 29 yr old female, about 2 yrs ago i had a hairdye disaster which completely destroyed my hair . it was left very damaged and so i had to cut it all off, the problem i have is that my hair grows extremely slowly, about 1cm over 6 months, my scalp wasnt damaged at all. its just bad luck that my hair got damaged aroung the same time that i noticed my hair growth slowing down, probably aroung when i was 25yrs old. i didnt have a good diet aroung that time and was under a lot stress. since my hair got ruined 2 yrs ago ive improved my diet and taking all my vitamins aswell. but its been 2 yrs now and my hair still hasnt started to grow healthily. in my early 20"s it grew about 2cm every month.iv not had a baby, iv had a blood test that shows my thyroid and iron levels and hormone levels are normal. i loose about 50 hairs every day, but it the existing hair is hardly growing. i heard minoxidil can help to speed up hair growth, is that true, because it causes hypertrichosis.
