i had the same problem! mine was like that because of heat damage so i cut about 4 inches off but my hair was sooo thin compared to when i was younger! ok what i did to get it back in good condition was use a henna treatment once a week follwed by deep conditioning. i did this for 8 weeks ans my hair was thicker and stronger...now i only need to henna once a month. also i used caster oil on my scalp and on my hair mixed with sesame oil. hope this helps in some way xx
