I picked up this product in Boots when calling in for a serum for the ends of my hair. This caught my attention tho and as it can be used as a serum too I picked it up... Two birds one stone and all that.
You apply the product to your hair when damp - I use it just before I blow dry - lengths and ends.
I was dubious at first with it being an oil, whether it would make my hair look greasy and although it states weightless I still had my concerns.
After first application and blow dry - I realised the product didn't leave my hair greasy at all and it did feel thicker and fuller. It also makes my hair feel thicker all day maintaining body that I would have usually lost.
Not stopped using it since I first tried it and I have to say I'm impressed. Plus it smells yummy too.
There's a full range of Biotin and Collagen products from OGX available from Boots and Supermarkets.
This one is around £6.99 but can usually be picked up in multibuy promotions.
