So my dermatologist says it's okay for me to dye my hair.

Earlier this year i acted on this advice, however i found that a lot of my new regrowth fell out when i was drying my hair (obviously after i had washed the dye out).

Actually, it didn't really fall out, it was more that i found the small hair on my towel after drying my hair. Like i had rubbed them off.

That was the first and only time i dyed my hair (it was a wash out dye, didn't have bleach in it).

What are…
