Scent: Scalp Treatment
Size: 2 Fl Oz (Pack of 1)
Thank you to the reviewers for leading me in the right direction. My scalp was going through it. I haven’t reached to scratch my head since the first day I used this serum. The effects last a very long time, even after washing. It’s had positive effects on my hair as well, as far as manageability and growth. It moisturizes without making my scalp shiny and greasy looking and it’s light on my hair. I haven’t had a breakout on my scalp and for that reason this is the only thing that I put in my head right now.

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.

Scent: Keratin

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.

Scent: Rosemary
Size: 2 Fl Oz (Pack of 1)
Amazing Results – My Hair Feels Healthier and Softer! I’ve purchased this Rosemary & Mint Hair Repair Oil a couple of times now, and I’m genuinely impressed. After just a few uses, my frizz was noticeably reduced, and my scalp felt refreshed. The serum is lightweight, non-greasy, and has a soothing minty scent that makes it feel like a mini spa treatment. I love that it contains castor and jojoba oil — it really nourishes the ends and adds a natural shine without weighing the hair down. I’ve tried it both as a leave-in and pre-shampoo treatment, and it works great either way. Also, a little goes a long way, so one bottle lasts quite a while. For the price, this is an excellent hair repair oil, especially for those dealing with dryness, split ends, or thinning hair. Highly recommend! ✅ Great for dry and damaged hair ✅ Refreshing scent ✅ Lightweight and non-sticky ✅ Works well for both men and women
