i think its true... its just a feeling i get cause somtimes my scalp ichy's, sometimes worse then others, it lasts less then 2 weeks though after that period i always have a feeling that my hair has gotten longer. then it doesnt ichy's again for a awhile. and i know that hair has different growth and resting stages. so i gathered that when my scalp ichy's its a growing stage, n when its not that its resting.
no proof, just somthing i noticed about my hair.

my hair: 3b, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
Oils and my own procuts are my hairs best friend
my hair goal length is bra strap length when curly.
