Keratin hair relaxers are a popular choice for those looking to straighten their hair without the harsh chemicals of traditional relaxers. These products use keratin, a protein found naturally in hair, to smooth and straighten strands. They work by breaking down the hair's natural curl pattern and sealing in the straighter shape. Keratin hair relaxers can last anywhere from three to six months and are suitable for all hair types. They can also help to reduce frizz and improve the overall health and appearance of hair.

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 relaxer or keratin?

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 the difference between hair relaxing and keratin treatment?

The most significant difference in hair relaxing vs hair smoothing results is that a formaldehyde-free keratin treatment will keep natural curls and waves while a chemical relaxer will entirely remove curls for a period of time.
