This is truly a miracle product! I started using about 8 months ago and has pretty much eliminated breakage & excess shedding. I have thick hair and have been bleaching for almost 8 years.. am amazed I have any hair left at all lol! I'd always see a ton of blonde hair on the bathroom floor, car seat, shower drain, and ofcourse in comb or brush when I blowdry. I would leave a trail of blonde hair where ever I'd go! This product has virtually eliminated shedding/breakage. I get maybe 2-3 strands in comb when I detangle, and no more blonde bundles on floor. I use every 4-6 weeks, immediately after bleaching (before toning). The smell is horrible, application is messy, and the process is very lengthy (takes me about 2 hours). The entire ordeal is a huge P.I.T.A. however the results are amazing and it is definitely worth it if you have chemically processed/bleached/damaged hair. This is definitely HG of protein treatments for me!
