I'm on day 15. So far I see a very slow shift in my mostly gray hair to a light orange shade. I look forward to continuing this treatment with the next bottle until the hair darkens closer to my original dark brown color, and hopefully go into maintenance mode after. Putting it on is messy and it tarnished my silver rings. Hope they can figure out a better way to pour out the liquid.
Amazing, in 7 days it worked! Will keep using this great product.
Ipak 4 zvjezdice, na početku sam dala 5 zvjezdica jer nakon što 3 tjedan ovo koristite redovito i kao je na uputama, vama će sigurno vratiti se boja, ostat će pokoja sijeda no rezultat je impresivan. Sad kad sam prestala koristiti vidim da mi ponovo raste sijeda :( tužna sam, očekivala sam ipak malo dužu promjenu, ovako izgleda da djeluje kao neka vrsta farbe. Iako sam razočarana što nisam dobila ono što sam mislila da ću dobiti, kupit ću ponovo i tretirati opet. :)

10 days in. Bottle nearly gone. I can’t tell if it’s doing anything yet. I think I’ll order another bottle.
Product ships quickly in spite of my continued speculation it works, in my case hair color is not consistent but I would be mostly white.
Ordering is easy. No results yet it has only been a month
Im truly satisfied with this product, it really works!!!
I was a little skeptical, but this would work, but my girlfriend and I have both been using it, and we are amazed with the results less than a month were both seen our hair changed to its natural color.
Product works great on hair and beard
This product is truly a game changer. Before I started using it, my hair was white but only in certain spots and I had to continually dye my hair to make it look good and smooth overall. After using this product, all of the white has smoothed in and is barely even noticeable. Now, I only need to go get my hair dyed if I want to. I started with 4 full days of not washing the hair but I couldn't do more than that because of my exercise routine, so I just did once a day for several weeks after that. It keeps blending more and more, the more I use it. One day I actually saw a hair on the table that was half white and half my regular brown color - it was such a cool moment. Keep up the good work and thank you so much! I'm really grateful a product like this exists.
The product ran out after 10 days (I bought one) and I saw only minor changes. I will buy more and wait for the results
It seems to be natural way to re-gain original hair colour ,without harsh chemicals. You have to be persist and be patient.It took longer for me ,about 4 weeks . I understand that results may vary from person to person.The applicator needs re-design to make it more efficient . The product is good in my opinion . However, there is no contact phone number and I am still waiting for a reply to my emails.
