9 Best Hair Straightening Shampoos 2023

Here’s my review of the top hair straightening shampoos including the best shampoo for straight hair sulfate free and keratin shampoo for straightened hair.

Hair straightening shampoos do not literally change the structure of your hair or straighten it. 

Actually, they help in reducing frizz, smoothening the hair, and sometimes weighing it down to make it look straighter than its natural structure. 

This is because they are usually composed of a higher amount of silicones and other binding agents.

How I tested the top hair straightening shampoos?

I have wavy, 2a hair that sometimes appears frizzy and wavy, and I like to use products like these straightening shampoos to keep them looking silky straight. So I tried out these shampoos on my own hair to see how well the formula worked. I also rated them on a scale of 1-5 on basis of the following factors.

  • Hair Straightening Ability – Firstly I checked if the shampoo had ingredients or a formula that would aid in changing hair structure to a straighter texture
  • Gentleness and Moisturizing – I also checked if the shampoo was gentle and sulfate-free and if had moisturizing properties
  • Hair Cleansing Ability – This is an important factor too as a shampoo primarily needs to clean oil, debris and dirt off your scalp and tresses.
  • Price – Obviously, I did not want to shell out an exorbitant amount as shampoos are something you use almost everyday.

However, if you have curly hair or natural, Afro hair you might need more than these shampoos to get that straight hair look.

Also, these shampoos can weigh hair down, so it’s important to maintain volume by removing product build-up weekly, if you’re using hair straightening shampoos.
