I’ve suffered from breakage through bleaching and this has really made a huge difference to my hair. It is pricey but it’s worth every penny!

Lifesaver for bleached hair
Wouldn’t be without this as a girly who colours her hair with bleach every 8 weeks and uses heat on it 3x a week. Brings to softness, smoothness, moisture back to my hair which gets a hammering!! So convenient to double shampoo and leave on in the shower for 4 mins whilst I shave and wash my body. Love it.

Tiny but lasts
I’ve actually got a really good number of uses out of the smallest size, I made sure to rub between my palms as tutorials stated, I’ve not seen a significant improvement in my hair overall but it does make it softer.
