I tried hair chalk, it causes my hair to dread.
I had the same problem with my hair. No mater what product I used my hair was like straw after lightening. It wasn’t even bleach at that time, it was just light hair color that strips a little. I tried bleach once and it was even worse, frizzy and breaking.
I know my hair holds braids. It’s just somthing they say because they don’t want to deal with my hair. A old co-worker once cornrowed my hair and it stayed for two weeks. It is just harder to “grip” fine hair so it takes more time and skill and they don’t want to deal with it.
