YUOLITA400ml Black Hair Shampoo for Natural Hair, Instant Blackening Dye for Men & Women, Plant Formula Lasts 30 Days

It works perfectly well

Nice product. Easy to use

Good, light stain on body

Says it lasts for 30 days, I bought this on the understanding it would wash out. I have just grown out all my box hair dye over 2 years, thought I'd use this as seemed natural, hair friendly and most importantly washed out. I now have regrowth from when I dyed it, so will now have to grow this out my hair, I've used a hair stripper on it and it's still there, OK lighter but still there. I bought the dark colour but after a week it turned an Auben colour, it stayed that colour, and it's stripped it a lighter Auben colour which I actually hate orange/red tones in my hair. My hair was untreated and natural prior to using this!!!

Love this product, works like a dream, this is my go to shampoo to cover my gray hair

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.

Exactly work

Excellent
