Keratin hair relaxers are a type of hair treatment that helps to straighten curly or frizzy hair. These products contain keratin, a protein that is naturally found in hair, to help smooth and straighten the hair shaft. Keratin hair relaxers work by temporarily breaking down the hair's natural curl pattern, making it easier to straighten with heat styling tools. They are a popular choice for those looking to achieve a sleek and smooth hairstyle without the use of harsh chemicals. While keratin hair relaxers can be effective, it is important to follow the manufacturer's instructions carefully and seek professional advice before use.

Frequently Asked Questions (FAQs)

1. Is keratin relaxer good for hair?

"Keratin is great for those who have frizzy hair and want long-term straight and smooth hair," she says. "The chemicals with keratin are a little less harmful than those found with other straightening treatments, like a relaxing treatment, which is very harsh."

2. Which is better keratin or relaxer?

Keratin treatment minimizes frizz and gives lustrous hair, lasting for 3-6 months. In relaxers, the structure of the hair is altered with special chemicals to give you silky, glossy hair. Keratin treatment lasts for 3 to 6 months, while relaxers last for 6 to 8 weeks, depending on hair care habits.

3. How long does keratin relaxer last?

As 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 6 months.

4. What is keratin Relaxing?

Keratin Treatment Keratin treatments are not relaxers but a smoothing treatment that infuses a special blend of hydrolyzed keratin deep into the cuticle. The Keratin is then adhered to the cuticle with a flat iron to relax the hair strands at the sub-cuticle layer.
