Not for the fine haired

If you have fine hair avoid this oil like the plague - It’s made for gods favourites. I can see the appeal... My hair feels super nourished, but my god, is this formula heavy! It gives my hair a great shine, but it also takes twice as long to dry and I’m still left with a damp greasy feeling afterwards. Very thick formula - not easy to work with. I used 2 pumps for 20” extensions 🤷🏼‍♀️. If I used it for the first time before having to go somewhere, a breakdown would be had.

Great All Rounder Oil

I’ve been using this oil lately to break the cast of my defining products and just adding oil to my kids and ends every day. I have curly 3c hair that ranges from fine to coarse and it’s been great! The teazturw has been great too, not too heavy

Fantastic- a little heavy if not careful, but YES!

I have pin straight, medium thickness hair. I’ve purchased this product several times! I love it, I think it’s great for the ends of my hair and preventing split ends. It also helps control flyaways. A little expensive for what it is, but I will buy again.

Really helps with frizz

It is heavy but that’s what my hair needs to not be frizzy. And I’ve tried everything. This one works.

Great for type 4 curly/coily hair

This oil is a GAME-CHANGER for my type 4 hair. Super lightweight and moisturizing. Keeps my hair moisturized whether I wear it straight or curly and a little goes a long way

Made my medium hair incredibly greasy - will be returning! I enjoy the rest of this line a lot otherwise :)

Not for me. I have fine hair and this weighed my hair down.

Too thick for a hair oil

Yes This hair oil made my hair soft but at the expense of having a VERY thick consistency which is a huge drawback for me. I feel it weighs down my hair more than other oils. Wouldn’t buy again

Bad Batch - smelled like canola oil

Normally love all things Amika. I got a sample and loved. The bottle I got eventually smelled like canola oil and I hadn’t had it that long. Can’t be returned because it’s past 30 days but please note that it can go rancid or be a bad batch.
