## Description

Product Description Redken Acidic Perfecting Concentrate Leave In-Treatment is Redken's most concentrated all-in-one formula for strength repair for all types of damaged hair. This conditioning leave-in treatment provides ultimate strength repair, intense conditioning and color fade protection. Featuring Citric Acid, this leave-in treatment contains a concentrated bonding care complex that reinforces weakened bonds within your hair to improve hair strength and resiliency. It repairs strength in damaged hair strands, provides heat protection up to 450 degrees, tames frizz, adds shine and reduces hair breakage. This pH-balancing leave-in treatment is specifically formulated with an acidic pH to defend against the negative effect of hair coloring, styling tools, and even water, which has a pH of 7, to balance hair's pH back into a healthy range of 4.5-5.5. The result? Healthier looking and feeling hair. Brand Story Redken is a professional haircare and haircolor company dedicated to providing science backed products, inspiring education and unparalleled creativity for consumers and stylists alike

Review: My go-to product for damaged, bleached hair - I love this product. From the very first use, you can feel a small difference, but by the third consecutive wash, my hair felt completely restored. My hair was extremely damaged and processed from bleach since I enjoy fantasy colors. I try many products, but I would call this one my “star product.” The ease of application is great — it spreads well and doesn’t feel heavy. The scent is pleasant without being overpowering. In terms of quality, it feels professional, and it definitely improves hair elasticity, making my hair softer and less brittle. The appearance of my hair looks shinier and healthier after each use. For longevity, I’ve noticed the effects last between washes, which is rare for repair treatments. The price is high, but in my opinion, it’s worth it for the results.
Review: HIGHLY RECOMMENDED for long hair!! - I have very long, very thick bleached/colored/grey hair. A small amount of this on towel dried hair-applied only from mid length to ends-removes tangles and works as a beautiful heat protectant. I do add a spray heat shield on ends WITH this! My hair is silky, shiny, has ZERO GREASY AREAS. Only issue is static afterwards, but that’s common in the desert. This stuff is wonderful for the $$. Compares to R&Co and ORIBE. (ORIBE IS BEST, but $$$)
