because this is THE best conditioner I have ever used. I’ve been using it for about 7 years now, I like switching up my products from time to time but I always come back to this one - there’s just no other product out there than can make my hair so silky and smell so so lovely. I’ve recommend it to all my friends and they love it! 

I’ve been using OI shampoo and conditioner for the past 5 months or so. My hair is dry and frizzy due to bleaching and hair styling but using these products has made a remarkable difference. My hair is far softer, less frizzy and it really brings out my natural curl (rather than my hair being fluffy as it was before). Product smells gorgeous and is really lightweight on my hair. It may seem a bit pricey but a little goes a long way. I ran out of product and had to revert to a store bought shampoo and conditioner as an interim measure whilst I waited for delivery and really noticed a difference (not in a good way). I’ll never use anything else now. Can’t recommend enough :)

I have very long, thick hair that leans on the dry side. This conditioner makes my hair feel soft and smooth and brings out my curls - and I need to use way less of it than I do with other products. It does have quite a strong botanical smell, but it's not unpleasant. The packaging is great, you can get even last bit out without any wastage.

I moved to the UK from NZ about 9 months ago, and my hair completely changed. It became all dry and frizzy. Can safely say that this conditioner saved my hair - it’s back to being soft and normal looking!

This must be the best conditioner I've ever tried. It leaves my hair ultra smooth and feeling strong. It's really thick too, so a little goes a long way. Great for over processed, bleached hair like mine!

Fabulous conditioner! I've got very dry and damaged bleached blonde hair and this conditioner really does the trick. It's extremely thick but dissolves lovely into hair, leaving it full of volume but silky smooth. Don't be put off my price, this conditioner will last months! Will definitely re-order.

Fabulous! My hair is easy to style now and looks like I’ve just left the salon! Luxurious and beautifully fragrant and doesn’t irritate my sensitive scalp. I use it with their shampoo, it’s such a treat and a little goes a long way so well worth it!

It's too heavy for my thin and straight hair. I need to use a microscopic amount unless I want my hair to look oily and almost dirty right after a shower.

Used to really love this conditioner until I realised it contained silicones, which ultimately dry out and damage hair over time. Will not be re-using and have switched to a Green People shampoo and conditioner.

I have thick, quite frizzy dry hair which needs A LOT of moisture, I didn't see any results I could not get with the previous less expensive brand I used, unfortunately.
