I’ve Lost Half of My Hair in 8 Months!

Hello,
I was wondering if i could get some advice on my hair loss. Over the past 8 months I have lost over half of my hair. I originally thought it was from dying it, so i stopped doing that all together. I’m 21 years old, and have always had a thick head of hair. We went to the doctors and we found out that i have an underactive thyroid, not by much, but for a 21 year old he said it should be higher, so now I have officially been on the medication for over a month now. My scalp is itchy, and I’m not sure if its from regrowth or loss of hair.

What is the deal with an itchy scalp? How long does it actually take for new hair to regrow? If it does, when will I see signs of it? Are there any other things that it could be?

thanks in advance! your site is very helpful!

If the cause of your hair loss and skin changes are from a thyroid condition, the hair loss may regrow in a year or so, but it may never recover to the point before the disease appeared. Unfortunately, all you can do is really just wait it out and keep following up with your doctors.

The skin condition needs to be looked at by a dermatologist. I couldn’t say if its due to your hair falling out (some people report that their scalp itches before losing hair, though that hasn’t been officially linked), but you wouldn’t see regrowth this quickly after starting treatment.
