Which shampoo to use after Loreal keratin treatment?

Can I use LOreal shampoo after keratin treatment?

Yes, you can use L Oreal shampoo after keratin treatment. However, it is important to use a gentle shampoo that does not contain harsh chemicals or sulfates. Sulfates are known to strip the hair of its natural oils and can damage the keratin treatments.

Can I use sulfate-free shampoo on keratin treated hair?

Yes, it is recommended to use sulfate-free shampoo on keratin-treated hair. Sulfates can strip the hair of its natural oils (argan oil), leading to dryness and damage. Keratin-treated hair requires gentle care to maintain its smooth and shiny texture. Switching to a sulfate-free shampoo can help preserve the keratin treatment and prolong its benefits. Look for shampoos that are specifically formulated for keratin-treated hair to ensure that they contain ingredients that will keep your hair healthy and nourished.

What happens if I use normal shampoo after keratin?

If you use normal shampoo after a keratin treatment, it can strip the hair of its natural oils and cause the keratin treatment to break down faster. Normal shampoos contain sulfates, which are strong detergents that can be harsh on the hair, causing it to become dry and brittle. This can result in frizz, split ends, and a dull appearance. Using a regular shampoo may also make your hair more difficult to manage and style.

To preserve your keratin treatment, it's important to use only sulfate-free shampoos and conditioners that are specifically designed for chemically treated hair. These products are gentler on the hair and will help to maintain your hair's smoothness and shine. Be sure to read the label carefully to ensure that the product is sulfate-free and safe to use after a keratin treatment.

Why is my hair still frizzy after keratin treatment?

There are several reasons why your hair may still be frizzy after a keratin treatment:

  • Humidity: Keratin treatments work by smoothing the hair cuticles, but high humidity can still cause the hair to absorb moisture and become frizzy.
  • Washing your hair too soon: After a keratin treatment, it's important to wait at least 72 hours before washing your hair to allow the treatment to set and fully seal into the hair.
  • Using the wrong shampoo or conditioner: Using a regular shampoo or conditioner that contains sulfates can strip the hair of its natural oils (argan oil) and cause the keratin treatment to break down faster, leading to frizz.
  • Touching your hair too much: The oils from your hands can transfer to your hair and cause it to become frizzy.
  • Damage to the hair: If your hair was already damaged before the keratin treatment, it may not be able to fully benefit from the treatment and may still be frizzy.

To reduce frizz, it's important to use sulfate-free hair products specifically designed for keratin-treated hair, avoid touching your hair too much, and protect your hair from humidity. Additionally, using a hair serum or argan oil can help to smooth the hair and prevent frizz.

Is it necessary to use same brand shampoo after keratin treatment?

It is not necessary to use the same brand of shampoo after a keratin treatment as long as you use a sulfate-free shampoo that is safe for chemically treated hair. However, using a shampoo and conditioner from the same brand as your keratin treatment may help to maximize the benefits of the treatment.

Best Sulfate Free Shampoos For Keratin Treated Hair

The best sulfate-free shampoos for keratin-treated hair are those that will clean your hair without stripping it of its natural oils such as argan oil and proteins.
