  • Conditioner
Size: 33.8 Fl Oz (Pack of 1)
Super fine and knotted hair- this works wonders. It’s thick and coats my hair perfectly. Soft on hair. Great price for value.

  • Best hair product on the market
Size: 13.5 Fl Oz (Pack of 1)
This shampoo really repairs your hair. After just a few washes, I can brush it with no more tangles, it's no longer frizzy or looking like an afro. I was nervous about paying so much but I am hooked. My late wife turned me on to this about 12 years and I am forever grateful. I just spent the last ten years homeless since she passed away but I recently found recovery and a job that allows me to afford it and within just a few washes, just like last time, I am no longer walking around with a tangled mop on my head. ... show more

  • Not worth the cost
Size: 33.8 Fl Oz (Pack of 1)
So I use the color protect conditioner (pink label) and it prevents frizz better than this product in my opinion. I have thick/wavey/can be frizzy if it’s humid out and I do not put the correct product on my hair. For me the correct combo is a good conditioner with a leave in spray, blow out creme, then heat protectant spray right before blowing out! ... show more
