Helps control frizz and adds shine without weighin
I really like this serum because it helps control my frizz and makes my hair look shiny without feeling heavy. A small amount goes a long way, and it makes my hair easier to manage. I also like the light scent. It’s perfect for everyday use, especially if your hair tends to get dry or frizzy.

Formula Change
I use to love this product ive purchased it at least 15x. I repurchase a week ago and the formula has definitely changed. it is 50% more runny. Left my hair super greasy even with a little bit of product.

Smooth, shiny hair with less frizz and no heavines
I really like this serum for controlling frizz and adding shine. It makes my hair feel smoother and more manageable without weighing it down or looking greasy. A small amount goes a long way, and it works well on both damp and dry hair. Great affordable option for sleek, polished hair.

Great product
Absorbency and consistency are great. Application is simple, use one pump, 1-2 drops of it according to the length of your hair and apply on your hair ends. It gives off shine, doesn't frizz.

ride or die hair product
this, is my #1 favorite hair product. as someone who uses very minimal hair products, this is the one product I will always purchase. it makes my hair so so soft and smell incredible. I wish there was a perfume with the same fragrance 😫 whenever I go to a new hair salon, i’m always asked how my hair is so healthy and well maintained, and my hair is the main compliment i receive ☺️ i’ve used this product since 2017 🤎

I love tresemme
This serum is lightweight but seriously powerful. It tames frizz instantly, adds smooth shine, and protects my hair from heat. A tiny amount is all I need..My hair feels nourished and polished, just like after a salon treatment....

Discontinued??
Has the original serum been discontinued? This new "blowout" is way too greasy. The original was perfect! Very disappointed!

Makes hair smooth, soft and frizz free!
I’ve been using the Tresemme Hair Serum for a while now, and I absolutely love it! It leaves my hair feeling incredibly smooth, soft, and frizz-free. The serum has a lightweight, non-greasy formula that tames flyaways without making my hair look oily. One of the best things about this product is how well it works for heat styling. I apply a small amount before using my straightener, and it enhances the sleek, polished look while adding a beautiful shine.
