Keratin hair treatments and products are probably the biggest breakthrough in the science of hair care in the past several decades. Most women don't care about the science part - they just love what it does for their hair! The use of these products has given them instantly smoother, more manageable hair. Hair is mostly made up of the protein keratin. For years, scientists have been struggling to find a way to recreate this naturally occurring protein in a lab in a form that could be used in hair products. If you look at the structure of hair, you see why. The hair is made up of two or three layers - the Medulla, the Cortex, and the Cuticle. The Medulla is absent for many fine haired people. The cortex is where all your hair pigment is contained. The difference between permanent and semi-permanent hair color is that permanent color penetrates into the cortex and stays there, where other color types just lay on top and wear off over time. When it comes to hair care, your biggest concern is the cuticle. You spend a lot of time and energy on that cuticle. That cuticle is the difference between big time frizz and smooth city. The cuticle is made up of many overlapping, scale-like cells. In a newborn baby, these scales are tightly bound and laying flat.
Through the damage, brushing, and other wear and tear these scales stand up and get rough looking.
Coarse hair tends to be thicker and have many more of these scales, roughly overlapping and giving the hair a kinky or curly appearance. Hair coloring is also disruptive to the cuticle, making it rougher. This hair is very porous. Keratin products fill in these pores and smooth them out. A tighter cuticle keeps moisture in the hair. Lanza Healing Haircare Healing Pure Keratin Infusion replenishes keratin amino acids to the hair and instantly rebuilds the hair's integrity.
Keratin Complex Infusion Therapy Keratin Replenisher opens the cuticle with a high pH formula, then infuses Keratin proteins and emollients into the hair, penetrating deeply and revitalizing. The cuticle is closed and the nourishment entrapped during blow drying.
