Alpecin Grey Attack Caffeine & Colour Shampoo for Men 1x 200ml | Gradually Darker and Stronger Hair | Controlled & Natural Looking Colour Effect for Less Greys | Against Thinning Hair

My mum came across this online somewhere and wanted to try it. It is on the pricey side but she loved it when I bought it for her. She said it works so instead of having to constantly dye your hair, this one helps fade it so the contrast is more gradient like. Easy to use and does what it says. It doesn't dye your hair but it does help to give you more time as compared to say a monthly hair dye session.FYI, her hair is black

It's better than the alternatives but it's not as effective as I would like. Maybe I should use it more often.

I’ve been using shampoo for a few weeks, and it’s okay—not amazing, but not terrible either.Pros:• It does reduce the appearance of grey hairs with consistent use.• Leaves my hair feeling soft and manageable.• The scent is pleasant and not too overpowering.Cons:• The results aren’t immediate—it took several washes to notice a difference.• Doesn’t completely cover grey; it blends them rather than hiding them entirely.• A bit pricey for what it delivers.Overall, it’s a decent product if you’re looking for subtle results, but don’t expect a total transformation. A good choice if you want something easy to use, but there are better options out there.

starting working almost right away without harshness. Healthy shiny hair is a definite plus.

This stuff is excellent, gradually reducing grey hair whilst looking like the hair actually still belongs to its owner.Takes a while to build up but if you run out or stop using the grey quickly returns.I only wish they had a version for my beard.

washes my hair well, does nothing for the grey hairs, i am aware, it is supposed to be gradual, but after several washes, no difference whatsoever, has been caused.Expensive and ineffective.

Works slowly,a bit pricey.

The people saying it doesn't work either aren't using it as stated or their hair is predominantly grey in which case this shampoo isn't going to work.The shampoo blends greys within your natural hair colour so they aren't as noticeable. It initially burned and thinned the hair slightly but I then reduced the time I kept it on for which was around 2 mins and the burning sensation went away.The product claims not to dye the skin as it doesn't work like conventional dyes, although it isn't a strong dye and doesn't stain the fingers or sanitary ware, it can over the course of weeks darken the skin. The main component responsible for the affects of this shampoo is an ingredient called 5,6 DHI and this is found in brown and black melanin within the hair and skin. When oxygen interacts with this ingredient it causes a dyeing reaction. If it's going to darken the hair it will also darken the areas of skin as 5,6 DHI is found within both skin and hair pigment, especially if you are of colour and can naturally tan, and the darker u are the more pronounced the affect on the skin is. I've now noticed there are 2 shades off different skin colour, where one part is at least 2 shades darker and it looks a little odd. For this reason I have to give it 3 stars as it does work but it dyes the skin over time as well.
