Dongsung Herb Speedy Color Cream Natural Black – Korean Herbal Vegan Hair Dye, PPD-Free, Ammonia-Free, Hypoallergenic – 100% Gray Coverage Odorless Dermatologically Tested Quick 20-Minute Application

This is definitely one of the best products I’ve ever used! I usually don’t write reviews, but I had to for this one. The secret is to leave it on your hair or beard for a bit longer. Instead of the recommended 10 mints, try leaving it on for 30 mints each session. The best part is that it’s allergy free. If you have sensitive skin, you won’t be disappointed with this product.

I’ve struggled for years with hair dye allergies—itching, burning, and red, irritated skin were the norm. I’m thrilled to report that this product caused zero allergic reactions for me. My brother, who also has severe reactions to standard dyes, tried it on my recommendation and had the exact same success. No irritation at all! Regarding the color: I see some negative reviews about coverage, but I believe it’s down to the timing. If you follow the 10-minute instructions, it won’t cover much. Here is my method for perfect results: Apply #1 for 10–15 minutes. Apply #2 immediately after and leave it for at least 30 minutes. The longer you leave it, the deeper the black. I even use this on my mustache, and the color lasts a solid two weeks. We are both very happy customers!

It said hypoallergenic. But after only one use, my scalp is SO itchy. Bad product. Try to avoid using!

I had so much trouble with hair dye allergies; this product was fantastic! Many temporary hair colors I have used never worked with my gray hair. The color stayed only when applied, and all the gray was left as soon as I washed. With all the uncertainty, I used this product and was amazed with the results. I literally saw black hair with no gray and no allergies at all! Thank you for the excellent product and for staying true to Amonia and PPD-free content.

It is good for sensitive skin but color changes to dark blue after few days. I tried different colors of the same brand and each one is changing color to dark blue after few days

Very good

It's a very good product i have been using it for 2 years now cause I'm allergic to other hair dye and it works very well

Tal vez sea un producto no alérgico, pero seguí con rigor las instrucciones y el pelo me quedó como un alambre y las canas tomaron un color amarillento. Le doy 3 estrellas porque cumple con el tema de que es inocuo, pero a mí no me resolvió.
