What is keratin? A keratin treatment, sometimes called a Brazilian blowout or Brazilian keratin treatment, is a chemical procedure usually done in a salon that can make hair look straighter for as long as 3 months. It adds intense glossy shine to hair and can reduce frizz. Smooth, shiny hair Keratin smooths cells that overlap to form hair strands, which means more manageable hair and less frizz. This makes for hair that dries with little frizz and has a glossy, healthy look to it. Keratin can also reduce the look of split ends by temporarily bonding the hair back together. Long-lasting results s long as you care for a keratin treatment by not washing your hair too frequently (2 to 3 times a week is enough), then your keratin treatment can last up to 3 months. More manageable hair Keratin treatments make hair more manageable, especially if your hair is particularly frizzy or thick. If you constantly heat style your hair, you’ll notice that with a keratin treatment your hair dries more quickly. Some people estimate that keratin cuts their drying time by more than half. Your hair may also become healthier and stronger since you can air dry it more often, saving it from heat damage. Keratin can strengthen and fortify hair so it doesn’t easily break off. This can make hair seem to grow faster because the ends aren’t breaking off. How to use it ?
