Amazing Keratin Hair Serum – Smooths Frizz and Leaves a Beautiful Shine!
I am absolutely in love with this keratin hair serum! Just a small amount transforms my hair, leaving it incredibly soft, sleek, and easy to manage. It works wonders for controlling frizz and smoothing down flyaways without making my hair feel greasy or weighed down. It leaves a gorgeous, healthy-looking shine and has a wonderfully subtle, pleasant scent. I highly recommend it to anyone looking to deeply nourish and restore their hair!

This tea tree hair serum completely transformed my dry, itchy scalp and frizzy hair!
I’ve struggled with dandruff and a flaky, itchy scalp for years, plus heat-damaged hair from daily styling. This Bellisso tea tree serum has been a total game-changer. The lightweight formula absorbs quickly into my scalp without leaving a greasy residue, and the cooling tea tree oil instantly soothes irritation. After just two weeks, my dandruff has drastically reduced, and my scalp no longer feels tight or itchy. The keratin in the serum also tames my frizzy ends and adds a healthy shine, making my hair feel softer and smoother than ever. I apply a few drops to damp hair before styling, and it protects my strands from heat damage too. I can’t recommend this enough!

Keratin Hair Serum – Heat Protection
This keratin hair serum has a lightweight texture that spread easily through damp hair without feeling greasy. During heat styling, it seemed to smooth strands and left hair looking shinier compared with un-treated sections. The applicator made it simple to distribute the serum from roots to ends without excess product buildup.In terms of protection, my hair appeared to handle blow-drying and flat-ironing without visible dryness or frizz afterward. It also rinsed out cleanly and did not make hair feel weighed down, which helped keep my overall styling routine manageable.On the downside, the scent was noticeable and may not suit people who prefer very mild or fragrance-free products. Additionally, while my hair looked smoother, the results were not as dramatic as some higher-end serums I’ve used before.Overall, this keratin heat-protective serum offers a balance of smoothness and ease of use for routine styling, and it could be a good everyday choice for those looking to add a bit of polish before using heat tools.

Leaves Hair Smooth and Shiny
“I really liked this argan oil serum. It helps control frizz and leaves my hair feeling soft, smooth, and shiny without looking greasy. A small amount goes a long way and the scent is very nice. Perfect for dry or damaged hair and great value for the price.”

Great product & it does exactly as advertised
My go to product for heat protection, easy comb thru, detangling, softness & shine. You can use it after a wash & condition , before or after blow drying, & before heat services such as flat iron. It has a nice fragrance , a lightweight feel, & does not feel oily afterwards. You will see & feel a difference in the softness, shine, & body of the hair with the first use. It’s a great product to help maintain & retain hair growth. It even softens the skin on your hands. I love this product & it’s a good value for the price. I highly recommend it.

Pretty good?
It’s been a few weeks of usage. Initially I noticed an immediate difference in hair loss, but now I’m not super sure anymore, however I certainly notice more hair growth and my hair has more volume overall! I do enjoy using it for some scalp and my dandruff has significantly reduced too! If you’re going to use it before bed, make sure to have some clothing or towel on your pillow or your pillow might absorb the oil like mine did.

Worst product, while using this product I lost the hair line. I’m deeply saddened by adverse effect on scalp.
