What the box says: Scott Cornwall Str8 Forward Super Straight is a permanent hair straightening kit with Keratin that conditions hair and can last up to 3 months. There’s no need for expensive salon treatments and daily hair straightening with Str8 Forward, it adds Keratin, the hairs natural protein, to help maintain its style, saving you time and money. The soothing chamomile and nettle will replenish any lost moisture and the collagen will fill in any voids resulting from general wear and tear. Curly, frizzy, bushy or unruly hair will be tamed and straight hair will no longer be an unobtainable dream. The science bit ... Str8 forward works by firstly breaking the internal bonds inside the hair – this phase leaves the hair open and able to accept both protein and a new shape. The part B Keratin phase then fills the hair with rich protein. With the new condition settled deep inside, the hair can then be straightened to create super smooth results. Finally the part C fixing cream re-connects those bonds creating that permanent ‘straight’ result. Not suitable for: • Henna treated hair • Heavily bleached hair • Hair treated with Lye relaxers • Afro Caribbean Hair There are 2 types of treatment if you have very curly, non colour treated hair, then Super Straight is the one for you. Alternatively for hair which has been colour treated, is sensitised or generally dry use the Extra Conditioning treatment. Result will last for an average of 3 months however longevity is based entirely on hair length, longer hair may find the straight sleek pattern lasts beyond 3 months, whilst it is common for very short hair to revert to their previous texture after 6 weeks.
