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.”

Very, very, good serum for scalp irritation.
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.

Great product, bad Packaging
This is a really great hair serum. I use this after I shampoo and wash my hair for the week. Has a great consistency helps cut down on the phrase when you use it just remember you have to reapply. I do not like the packaging because if your bottle Falls over or if you're traveling and it tilts it will leak almost the entire bottle. This is happening to me more than one time. Which is why I was hesitant to buy it again but the product is good.

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.

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

This product was recommended by my doctor. I am still using it and don't see a difference yet.

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!

FANTASTIC PRODUCT for split ends and damaged hair!!!!!
I really like this product. I have very thin, straw-like hair and use this every time I get out of the shower. It doesn't leave my hair oily which is a huge plus, but does leave it soft and helps smooth over my split ends. My hair has had a lot of damage over the years due to flat iron usage so this really is a game changer for me. It doesn't leave a weird smell, I love how soft my hair feels, and it looks and feels so much healthier! I have found that it works really well with just few pumps of it in my hand massaged into my damp hair after a shower. Highly recommend and the price is great for what you get!

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.

Didn’t work on me
Worst product, while using this product I lost the hair line. I’m deeply saddened by adverse effect on scalp.
