Why Should You Do A Keratin Treatment?

A keratin treatment, also referred to as a Brazilian Blowout, is a procedure that restores the hair and increases shine by adding keratin to the hair.

This treatment is beneficial to those who have frizzy or curly hair and are looking for sleek and shiny hair instead.

Some people simply like to change their appearance and others like to get this treatment done prior to holidays and big events.

The results can last up to 3 months, so that’s something to take into consideration before going ahead with the procedure.

Here are some of the main benefits of a keratin treatment:

  • Reduces frizz
  • Hair becomes more manageable
  • Hair becomes shinier and smoother
  • Less blow drying time
  • Hair may be less prone to breakage due to the keratin strengthening the strands
  • Long-lasting results

While there are some benefits to this treatment, it’s not suitable for everyone. Pregnant women and those with scalp conditions will have to avoid this procedure due to the chemicals that are used.

Should I use Leave-in Conditioner On Keratin Treated Hair?

After your keratin treatment, you need to be mindful of everything you apply to your hair.

You will need to avoid shampoos containing sulfates and harsh chemicals and opt for gentler hair products instead.

You also need to ensure that you give your hair enough hydration and moisture to maintain the results.

One product that you should add to your hair care routine is a keratin-friendly leave-in conditioner.

These conditioners are designed to protect keratin-treated hair and ensure that your hair remains silky and shiny for as long as possible.

What Type Of Leave-in Conditioner Is The Best?

Some leave-in conditioners can be damaging to keratin-treated hair, which is why you should always check the ingredients carefully.

Avoid sulfates as these can strip the hair, making it appear dull and lifeless. Another ingredient to avoid is sodium chloride because it will break down the keratin in your hair very quickly.

There are often two types of leave-in conditioners: creams and sprays. A spray is typically lightweight, making it a better option for people with thin or fine hair.

Whereas a cream will often be heavier and more suited to dry, curly, or thicker hair. Your hair type should always be taken into consideration when choosing a leave-in conditioner.
