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.

How can I take care of my straight hair?
Straight hair can be difficult to take care of – it’s prone to frizz, dryness, and damage. To avoid these problems, you’ll need to follow some basic hair care tips:
Use a conditioner – Conditioners help to restore the moisture and elasticity lost in straight hair, which can help to prevent frizz and dryness.
Avoid using heat on your hair – Heating your hair can cause it to become dry and frizzy. Instead, use a humidity cap or a humidifier when necessary.
Avoid using harsh chemicals on your hair – Many straight-haired people are unaware that many harsh chemicals used in styling products are damaging to their hair. Stick to gentle products that won’t harm your locks.
Protect your locks with a good hairstyle – A good hairstyle will help protect your hair from the elements and make styling easier. Choose styles that are moisturizing and protective, such as braids or updos.

Hair straightening shampoos are fantastic for reducing frizz or getting your 1c or 2a hair looking smoother.
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.
