Yes, I paid 85$ for shampoo, but nothing has ever helped my dry, curly, damaged hair. All other shampoos seemed to just wash out of my hair. After the first use I noticed a difference and by the second use my hair was noticeably improved (hydrated, smoothed, and silky). It still has some repairing to do but the salon told me that by the second week it restores you hair to its "virgin state, before you used damaging products." So far so good, I'm looking forward to it working!
(Ask someone at your salon to explain the technology this product uses because it's quite interesting and good to know for your hair.)
