Amaizing result
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

Great product, even for fine hair!!
I am giving this a five even though I've only been using it for a little over a week because I was not expecting the other benefits this added to my hair! I've been experiencing hair loss for the last 2yrs and now it is at half the volume it was, flat/lifeless and greasy/dry no matter what conditioning/protein/oil treatment I've done. I have seen what looks like a small amount of possible hair regrowth at my part (too soon to tell for sure but I'm sure I'll see thise results soon). This oil is OMG for my hair!! When I listed the above issues with my hair I mean it is flat/greasy/dry right after washing and blow drying and I feel like I can't even wear it down. Now my hair has the same silky texture from root to ends and has almost doubled in volume overnight! I massage 3-4 drops into my hair after washing, let sit for 5mins and then blow-dry my hair where I'm sure some oil gets brushed through the strands and I haven't had to use any product in my hair because it is fluffy and gorgeous and dry in a healthy way I am soo happy! I have fine hair and it does not leave any residue or weight behind in the hair at all, slight herbal scent that actually goes away once your hair dries. I am also making my bf use this, he is 25 with significant hairless along his hair line. His hair is alot more curly/glossy and healthy looking, not the lifeless flat thin waves it started looking like. I'll post back another update for readers on the hair regrowth (the important part lol) but otherwise a great product that has saved my hair either way!

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.

So smooth
Luv this little bottle. Doesn’t leave the hair sticky or greasy. So smooth The only thing is that it’s a glass bottle so be careful to not drop. If ur crafty the bottle can be up cycled.

Magic for fine hair
The scent is wonderful it's not overpowering. I don't like to over style my hair and a little of this really tames my fly aways. I have fine hair and this doesn't weigh down and flatten my hair

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.
