Keratin that is present in the hair, scales and in the epidermis of the skin is hydrolyzed in the presence of alkali (at pH values greater than 11.5). The disulfide bridges found in keratin protein are cleaved but can be reformed. Long periods of liming will result in hair removal. The main removal of keratin is performed during the unhairing ...
The solvent to use is dependent on two factors: the agent that is causing the stain, and the material that has been stained. Different solvents will dissolve different stains, and the application of some solvents is limited by the fact that they not only dissolve the stain, but also dissolve the material that is stained as well.

Alpha-keratin (α-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents.
Prior to shaving, Moustafa recommends applying salicylic acid to the skin and allowing the chemical exfoliant to sit and dissolve excess skin cells and keratin that may get trapped in the hair ...
For moderate to severe cases, the affected areas should be hydrated (moisturised) with warm water or compresses for 5-10 minutes. Softening preparations are then applied once a day until the excess keratin is removed. In dogs with severe hyperkeratosis and a significant excess of keratin, it is removed with scissors or a blade.
A keratin treatment is a semi-permanent hair straightening method that aims to smooth and straighten frizzy or curly hair, says Ross Kopelman, MD, a board-certified hair surgeon at Kopelman Hair ...
A chemical depilatory is a cosmetic preparation used to remove hair from the skin.Common active ingredients are salts of thioglycolic acid and thiolactic acids.These compounds break the disulfide bonds in keratin and also hydrolyze the hair so that it is easily removed.
To do this, a surgeon uses “micro punches” (tiny holes) to remove hairs from the scalp with minimal scarring. The advantage of FUE is that it doesn’t leave a large scar. Instead, it creates ...
