What the gurus are saying

One expert finds it spreads smoothly through hair and works well for their routine, though a small amount goes a long way and the price is steep. Another has warmed to it over time but doesn't consider it essential and plans to explore less expensive alternatives once their bottle runs out. The takeaway: it may work nicely for some hair types, but the cost means it's worth trying a patch or smaller size first to see if it's worth the investment for the individual.

"My hair also just really loves the Redken Acidic Perfecting Concentrate Leave-in Treatment. My hair loves this range, it's great for me. It is pricier. I tend to use like a much smaller blob, maybe like two Tic Tacs in size. This one just seems to spread a bit better as well. I personally find that if I use these ones on dry hair it kind of feels like I'm spreading it all around the outside of my hair and it's not like in the middle, but [...] this one just spreads really really nicely."

"I've been using this Redken Acidic Perfecting Concentrate for over a month now. It is intended for people who have color-treated hair or damaged hair from a lot of chemical processing. It has technology in it that allegedly reapproximates those damaged bonds and it also acts as a heat protectant. For me it's not been as good in terms of the bang for my buck I get as far as the styling benefit that it provides."

"I'm still using this Redken Acidic Perfecting Concentrate Leave-in Treatment. I've kind of come around to it, but it's definitely not my Holy Grail."

"It has five percent conditioning care complex. You apply it to clean damp hair, leave it in, do not rinse, and style as usual. It says it's an intense conditioning, heat protection, styling aid, hydration, intense protection. The scent smells kind of like a candle, but not as nice as the Moroccan oil. I don't feel like it goes into the hair as well as a styling cream. Fragrance is a common allergen, a contact allergen, it's one of the most common contact allergens when it comes to personal care products."

"I'm coming into my hair with this Acidic Perfecting Concentrate from Redken, it's like a leave-in conditioner for me. It's got some ingredient in it that allegedly will put the disulfide bonds back together if your hair is damaged from heat styling and chemical treatments like getting your hair colored, but I just use it as a leave-in conditioner and it's okay."
