Strong, flexible, and radiant hair is something many of us aspire to. Over time, factors such as heat styling, chemical treatments, and environmental damage can weaken the hair’s structure, leaving it dry, brittle, and lacking vitality. This is where a key protein naturally present in our bodies—comes in: keratin. In this article, we’ll explore what keratin is, how it benefits hair health, and which hair types can benefit most from it. We’ll also introduce Redefine’s Keratin Series, designed to provide professional care for repairing and strengthening hair.
What is Keratin?
Keratin is a fibrous protein that forms the main building block of our hair, skin, and nails. In fact, about 90% of each strand of hair is made up of keratin. This protein is responsible for the hair’s inner and outer structure, giving it strength, elasticity, and resilience. When hair has sufficient keratin, it looks smooth, healthy, and shiny.
Why Does Hair Lose Keratin?
There are several main reasons keratin levels in the hair may decline:
-
Chemical treatments: Coloring, bleaching, straightening, or perming damage the cuticle and deplete natural keratin reserves.
-
Heat styling: Frequent use of straighteners, curling irons, and blow dryers at high heat weakens keratin bonds.
-
Environmental damage: Sun exposure, saltwater, chlorine, and air pollution all contribute to keratin breakdown.
-
Poor care: Using unsuitable or harsh products strips the hair of its natural protection.
When hair loses keratin, it becomes more fragile, prone to breakage, less elastic, dry, frizzy, and dull.
The Benefits of Keratin Treatment for Hair
Topical keratin, delivered through dedicated haircare products, can work wonders:
-
Repair & strength: Penetrates the hair shaft, filling cracks and rebuilding from within. Hair becomes stronger and more resistant to breakage.
-
Moisture & softness: Restores natural hydration, leaving hair soft, silky, and more manageable.
-
Frizz & static reduction: Smooths the cuticle to minimize frizz and eliminate static, giving hair a polished look.
-
Shine boost: Healthy, keratin-rich hair reflects light better, resulting in radiant shine.
-
Future protection: Creates an extra barrier against heat and environmental damage.
Which Hair Types Benefit Most from Keratin?
Keratin-based products are especially recommended for:
-
Dry, dehydrated hair: Restores natural moisture balance.
-
Damaged, brittle hair: Repairs weakness from heat, chemicals, or neglect.
-
Straightened hair: Especially after keratin-based treatments, ongoing maintenance with keratin products helps preserve results and keep hair healthy.
-
Frizzy hair: Reduces frizz and creates a smoother, more controlled look.
-
Color-treated or bleached hair: Strengthens and protects fragile strands.
