Review: 😃 - This product leaves my hair, nice and soft. It does what it said it gets rid of the frizz and give your hair a nice shine.
Review: 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

### ⭐⭐⭐⭐ Worth the money!
*by E***E on October 7, 2025*

I think this was a great purchase for the price! I don’t feel like it really has much of a scent. My hair is noticeably softer though and it does manage the frizz pretty decently. I’ve used it on both wet and dry hair. Very easy to use! There are definitely better products out there, but this one’s pretty great for the price!
