TRESemmé Keratin Smooth Shampoo Review


My only regret about Tresemme hair products is that I should have used them much sooner. For a long time I tried everything to straighten my curly hair, which only made it drier. When I tried to focus on letting my natural texture shine, things got better. I have extremely dry and frizzy curly hair and it only looks naturally good when heavily moisturized.

The first Tresemme product I tried was the Tresemme Keratin Hair Mask. It worked so well for me that I decided to buy the shampoo from the same series. The best thing about this shampoo is that it has low sulfate content. Sulfate is added to shampoos to a large extent so that they produce strong foam. But the bad thing is that they strip your scalp of its natural oil and dry out the natural hair layer. This is why color-treated shampoos are different, as in traditional shampoos the color layer fades.

What is it?

Tresemme's Keratin Smooth Shampoo with Argan Oil combines the strength of keratin with the nourishing properties of argan oil and features a formula with reduced sulfate content. This formulation not only ensures smoother and smoother hair, but also effectively fights frizz for up to 3 days. Due to its lower sulfate content, it is suitable for both natural and chemically treated hair.

Performance of the Tresemme Keratin Shampoo

Fragrance: It has the classic Tresemme scent with a subtle floral undertone. Although the scent is slightly strong, it could be overwhelming for some people. The scent lasts all day.

Packaging: The Tresemme Keratin Smooth With Argan Oil Shampoo is packaged in a sturdy yet flexible opaque maroon plastic bottle that features a secure black snap closure. The bottle design ensures easy product removal and the easy-seal lid prevents leaks or spills, ensuring a hassle-free experience. The compact design of this smallest packaging is available in various sizes, making it practical and travel-friendly. Detailed product information can be found on the back of the bottle.

formula: The shampoo is a bit creamy, but also a bit runny. It is completely white and has a slight pearlescent sheen. It glides smoothly on my scalp, but I would recommend adding a splash of water before applying. It lathers well and does a great job of removing dirt and oil from my scalp. I usually do about two turns since I have thick, shoulder-length hair.

Result: I absolutely love this shampoo! It has been a game-changer for my curly hair and the best part is how effortlessly I can detangle my hair after using Tresemme's Keratin line. Anyone with curly hair knows what a relief it is to achieve these results without breaking the bank.

Final thoughts

Tresemme Keratin Shampoo has become my go-to for caring for my curly and frizzy hair. It works wonders for taming unruly curls and making them smoother and more manageable. However, I have noticed that with heavily oiled hair, it requires a significant amount of shampoo to thoroughly clean it and remove the oil. This might be something to consider for those who oil their hair regularly, as it can lead to faster product depletion. Still, the overall effectiveness in taming my curls makes it a worthwhile choice, especially for those looking for a solution to curly or frizz-prone hair. Here are my final pros and cons of this shampoo:


  1. Budget friendly
  2. Available in different sizes.
  3. Efficient cleaning
  4. Leaves hair frizz-free and supple
  5. Keeps hair moisturized


  1. Not SLS free
  2. Has scent
  3. Not for oily scalp and fine hair

Does Tresemme Keratin Shampoo straighten hair?

This shampoo does not have a smoothing effect on the hair. It only makes curly hair frizz-free and smooth. It especially helps in detangling the hair. If I had frizz-free, shiny, bouncy curls, I wouldn't worry too much about straightening anyway.

Will I buy it again?

I will definitely repurchase this shampoo. In fact, the duo of this shampoo and Tresemme hair mask is a combination that I won't be parting with anytime soon. The results are just too good to pass up, which is why it's becoming a staple in my hair care routine in the long run.
