## Customer Reviews

### ⭐⭐ 







  
  
    Looks like the box and its contents have been dragged through a hedge.
  

*by H***Y on Reviewed in the United Kingdom on 6 March 2021*

What a shame I never had a chance to use this product because it's just what my hair needs, but I never got around to it because most of the contents of the box, especially the gloves in the plastic cup and the box was in terrible condition.  The seal on the box lid which was used to keep the contents in had been removed and the condition of this parcel wouldn't have been good enough to be sold on a flee market second hand let alone brand-new for this price.

    Very  Bad Itching
  

*by S***A on Reviewed in the United States on 20 November 2019*

What a waste of $50, bought the 2, like they say to do. Couldn't do the test till now, cause my husband died. The itching was insane. Too long now, can't even send it back. Horrible product. Threw it out!

### ⭐⭐⭐ 







  
  
    Pretty color but kinda a waste of my money
  

*by E***A on Reviewed in the United States on 17 September 2018*

I did love the color outcome but it washed out fairly quickly Like within a couple weeks
