Keratin Therapy Hair Colour Shampoo – Temporary Hair Dye, Lasts 4 – 8 washes, Ammonia and Oxidant-Free, Pack of 6x40 ml (Chocolate)

This shampoo is a godsend! I stumbled upon it as I was looking for something to temporarily cover up my grey/silver roots. I didn't want to use a permanent dye as I'm going lighter when I next see my hairdresser, but I have to wait until the end of the month to see her as she's fully booked. My hair is dark but is naturally silver now, so my roots were just too bad. I didn't think this shampoo would do much to be honest, but I washed my hair as normal without conditioning it, applied this product and left it for 45 mins. It comes out of the sachet as quite a thin liquid and I thought it would be dripping down my face and back while I was waiting for it to work. Surprisingly it didn't! In fact, even though you put it on like a shampoo ie without taking care not to get it on your ears etc., I found that it didn't stain my skin at all. Much better than a permanent dye. I washed it off with my usual shampoo (even though this is a shampoo), conditioned it and dried it as normal. I could not believe the difference. There are places where it has taken better than others, but my parting, around my crown and face all took really well and those were my areas of concern. It doesn't cover the grey completely but it blends it in such a way as you just can't see the roots at all and if it has managed to cover my silver roots to blend in with my very dark brown hair, it'll blend any grey. Fantastic product. Definitely a game changer in between visits to the hairdresser!

Photo 1 - hair prior to dyePhoto 2 - comparison of roots before and straight after dyePhoto 3 & 4 - straight after dye was usedPhoto 5 & 6 - hair & roots after the 9th wash.I've been growing my grey out for a few years but wanted something temporary for a birthday party. I've made the mistake of colouring my hair a few times over the years and regretted having to grow out the colour all over again each time, so the reviews that stated the product barely lasted long at all were what swayed me to give this a try.Using it was fairly easy, I was surprised at how runny the dye was and I just used it like a shampoo. I used one sachet and left it on for 20mins (the reviews stated the longer they left it on the longer it stayed on so I went for the minimum time per instructions).The coverage was pretty great, I could still see some grey areas but I believe that was due to my application and should have probably used 2 packets with the length of hair. The colour was great and what I expected from 'Chocolate Brown'The reason for my 1 star is because I am now 10 washes in and the dye is still clearly on my hair. I wanted something extremely temporary and I'm now very concerned I'm stuck re-growing my grey hair out for the next few years again! As in the photos, I have quite prominent grey roots which is making me quite unhappy and I would say the colour on top has started to go kind of purple. It has definitely faded some and I can see some of the grey coming through in places but I would have expected it to be mostly gone by now.I'll probably give it to wash 20 before trying one of the colour remover boxes.

Loved this product, it does exactly what I wanted it covers grey hairs and gives my hair a lovely healthy colour. I’ve ordered two sets of these and will be back for more.

I used the platinum blonde over some grey hair and it was purple. (I don't mind purple, just hoping for blonde.) It makes sense as a toner and I understand from re-reading the description that it is intended for use over hair that is blonde, not grey. However I would not recommend using the platinum blonde over grey hair unless you are aiming for purple.

I get my hair coloured at the salon but as the weeks go on the grey/white starts to show around my temple. Rather than putting on a whole root touch up box for about a week I decided to try these. The colour goes well with my own dark brown short pixie cut, its easy to use but sooo messy. You have to shampoo your hair, then add in and mix until foams up (which mine didn't) and then leave for either 20 mins or 45 mins. Now sitting around with this stuff literally running down your face/neck isn't pleasant so I put a plastic shower cap over they dye and then wrap a towel around as well - then find something good to watch on tv and just sit. Smells nice when rinsed off and does last the 8 washes (if you leave for 45 mins). Would recommend but be prepared as messier than permanent/semi-perm dyes which I have used and can move around without the dripping.

This demi permanent hair colour amazing. I've been using permanent hair dye far too long and my hair needs a good rest so I gave this a go. The first one I used I only left on for 20 mins. It took lovely but washed out quick. the second one I left on for 45 mins and it lasted a lot longer. Around 3-4 weeks longer. It did leave my hair extremely hard to comb afterwards. The third time I used it,I mixed the sachet with a generous blob of conditioner and again,left it on my hair for 45mins. The result was amazing. My hair got a deep condition at the same time as it got a lovely colour. I'm so happy with this product. I will always use it. Great value for money too as you get 6 in the box

Love it

Although easy to use and initially the colour was just what I wanted ,BUT the first time I shampooed my hair, it didn't lighten it, it turned it purple. I washed my hair every few days (ordinary shampoo and conditioner) it didn't fade at all. I ended up purchasing a hair dye remover but that only lightened the purple. I then had to go to hairdressers for them to rectify, firstly using a neutralising agent, then putting a colour on, at a total cost of £120. so much for a quick colour hair change, never again would I use this product

Das Produkt ist hervorragend.

Sur tout m était bien les gants si non vous aurez les main mauve et en plus laver 4 fois mais cheveux et le mauve ne veux pas partirGrrr

Il prodotto è ottimo .Sui miei capelli sale e pepe però fa risaltare il grigio e non il bianco platino

Produit un léger ton rougeâtre. Je suis passé à la nuance blond foncé.

No cubre las canas por más tiempo o más veces que lo uses
