Kristin Ess Hair Gloss in Bittersweet, Dark Brunette - 4 Week Semi Permanent Hair Color for Women - Shine - Hair Dye Glaze

I have grays (or should I say "whites" ) coming in on my sides and underneath where the hairline meets my neck -- and a few sporadic ones overall. My sister recommended this product because I am not ready to commit to full-on dying my hair. The product states that it does not cover grays, but I will tell you it made a HUGE difference as you can see by the pics. It did wonders for the sides of my hair as well - not total coverage but took the "white" out and made the hair more golden and blended. To say you can use it in the shower is a bit optimistic. I don't spend that much time in the shower, and it's a bit messy ( it will stain a fabric shower curtain), so if you're like me, you need a plan for application (and a shower cap) while the magic works. The smell is pleasant - not toxic - and my hair was soft and shiny after use. I would say it made my natural color darker, but I think it was the correct shade for me. I used it on 3/8/26 and I plan to use it again next weekend, so the "4 week" longevity seems accurate. If you're on the fence, and not ready to commit to true hair dye, go for it -- it's temporary!
