I was in CosmoProf today and noticed Schwarzkopf has a product called BLONDME Pre-Lift Kera Protector for around $30 for a small bottle. It's meant to be sprayed into the hair, and then dried without rinsing, before applying lightner to the hair. I don't use this brand and had never heard of this particular product but was intrigued. On further investigation I found this description:
"Apply Pre-Lift Kera Protector before lightening or coloration for maximum and long-term hair protection. Its reactive silanols builds an invisible shield around the hair surface to reduce potential chemical damages during the lightening process and preserve the look and feel of the hair. This protector provides maximum hair protection for 50 percent less hair breakage and split ends during lightening and 30 percent higher care during coloring, when compared to previous BLONDME color. When using Pre-Lift Kera Protector before BLONDME lightening and BLONDME after care regime, the hair is two times more resistant, smoother, softer and shinier, delivering even blonde results from roots to end."
I was wondering what cosmetic scientists would have to say about this product and it's purposed benefits. Is it something worth investing in when bleaching someones hair? I already use Olaplex, but would this be another good addition to my products used with lightners?
