Back to brittle
I’ve given this product a chance 2x and got the same outcome. It’s just not for me. It drys my hair out so bad and seems to make it more stif and stressed looking. I’m 4 months post bleached hair and my hair was gaining its texture back until trying this again I have to say olaex agrees w my hair nicely.
