400ml Black Hair Shampoo for Natural Hair, Instant Blackening Dye Hair Dye Shampoo Black Color for Men Women, Mild Plant Formula Lasts 30 Days

It is cheap and easy

Very good product. Effective

Its basically hair dye in a convenient bottle. It does last a long time though. Calling it shampoo is a bit of stretch.Value for money, only if you can't be bothered to mix your own solution.

I was use many hair dye products. But I realise this is a best one. Today I’m order another bottle. Highly recommend

leaves marks on the skin

It does work

I've been using this for a few months now. It saves all the faff of mixing dyes. Add as much as you need, leave for around half an hour, rinse and done.

It is often advertised as herbal and natural etc but it will contain some PPD like all the others. The other issue it it is never the same formula (very obvious from its appearance). Sometimes the non-dye is a clear liquid and currently it's a white foam like substance. The dye also changes colour (from yellow to brown) between batches and even the smell changes. It is also not usually similar to the packet version (25ml) even though they are ostensibly the same brand and product (the dye in the packs is usually more yellowy with a stronger smell). It always seems to work well within the times stated (4 minutes is normally good for dark brown rather than very black). There was also a bad batch last year (all places selling it seemed to be trying to sell the same batch - even ebay and multiple vendors on amazon) that had the dye solidified and almost impossible to remove from the bottle as instead of liquid it was in a strange foam-like stringy consistency. All this doesn't bode well for the manufacturing quality but at least it works.

Je suis très contente de ce produit il teint vraiment les cheveux blancs moi qui suit obligé de faire les racines tous les 10 jours je suis très contente enfin un produit de ce genre que je recherche depuis des années je devais allé à l hôpital urgence et j avais toutes les racines de mes cheveux blanches ne voulons pas me présenter ainsi et surtout j avais peur qu on me garde 1 semaine à l hôpital j ai fait ce shampoing car trop fatiguée pour faire une couleur j ai été époustouflé de voir le résultat si facilement appliqué malgré ma fatigue j étais super contente après 30 mnJ 1ai seche mes cheveux et je me sentais mieux pour pouvoir me présenter aux urgences

Actually very good. Works fast so don't keep it long. Doesn't colour the skin. The colour is very black and stays doesn't fade away in some sort of gringe colour

Il prodotto dà un bel risultato

Nice..will buy again

Waste of money. This should fall under dye not shampoo…
