90% of every hair consists of keratin and (dependent on the moisture in the environment) 5–10% is water; minor hair constituents are lipids (fat), pigments and minerals. Keratin is a fibrous protein which gives strength and elasticity to the inner and outer hair structure - it is therefore no wonder that shampoo with the protein keratin is great for the hair. The keratin protein consists of long peptide chains which form strong filaments. The composition of the peptide chains determines the structure of individual filaments. Hair filaments may turn around their long axis, bend or even fold.
Intact keratin is not only elastic but also insoluble in water. Keratin is able to tolerate extreme temperatures both on the high and low side. Thanks to keratin, hair is built to withstand (or at least tolerate for a while) the hot rays of the summer sun and bitter winter cold as well as the heat of styling aids like curling irons, flat irons, hot curlers and other heated tools.
Hair with sufficient intact keratin is well equipped to withstand the onslaught of environmental stressors. Still, persistent exposure to stress will finally do some damage to the long strings of keratin, which are responsible for keeping the shape of every hair intact. Once keratin is broken down into small enough strings, it becomes water soluble and will be washed away. This is where keratin protein shampoo comes in.
Keratin Shampoo Strengthens Hair
If your hair is damaged or if you want to straighten and strengthen your hair or make it more resilient to stress, there is no reason not to enjoy the advantages of keratin shampoo and styling products.
Keratin is added as an intensely potent ingredient to hair care products because it strengthens hair by improving the hair structure from the inside out. As a result, using shampoo with keratin can help your hair to regain its healthy, natural structure. Keratin fills gaps and breaks in the hair shaft to make hair suppler, shinier and easier to style.
Keratin shampoo is not the only option when it comes to strengthening the hair. Keratin is also found in styling aids like mousse and hairspray. All these products may contain liquid forms of keratin, which are identical to the natural keratin found in human hair. Using styling products or shampoo with keratin also helps to provide the hair with optimal protection against moisture loss. What’s more, you will also enjoy the ease of achieving excellent styling results.
