Okay..

Okay BEWARE this stuff is kinda an investment. I think i’ve rebought over 10 times in the last 6 months so just know..also because of the like no shampoo stuff before your gonna loose hair no matter what. I love the way my hair feels after and yeah okay in some ways I actually do think I see a difference after this long but it’s so expensive and it barley lasts like it’s over so quick bc you have to use like 4-6 pumps for your hair depending on how much you have. I wouldn’t say mine is super thick but not thin. I just feel like there should be a better option I just don’t know what that is. That being said it’s also a time commitment this isn’t something you just pop on and get to blowdrying. I do like it but unless you have the money and want to reallyyyy try I’d say don’t do it.

WORKS

I've been bleaching my hair since 12y/o and dying it ~once a month assertiveness 16y/o and my hair has genuinely not felt or looked this soft and healthy in literal YEARS. the price is well worth the product chat, my hair was FRIED after I bleached it 4 times in one night (black box dye + bleach ≠ anything good happening) and now my hair is softer healthier and hopefully stronger. guys, buy it
