Control GX + THK Thickening Beard Wash with Grey Reduction, Alpha Keratin Helps Beard Growth, Thickens Hair Up to 20%, Works with Every Hair Texture, 4 oz

Careful. This product works better than the Control GX. What I mean as being careful is that don’t let the product stay on your skin longer than 5 minutes. It will stain your skin. I was able to reduce my grays significantly in 3 days. Compared to others that I’ve tried, where I have to let it stay for about 10 minutes. Yes, it can stain your nails, obviously. It’s the same composition of hair. Recommend buffing your nails or wear gloves prior. Not sure about thickening your beard as I don’t have thin beard. I didn’t get any skin reactions nor itching.

Works very good but very messy. Has to be worked into beard and facial hair and left for 5mins then washed off. Advantages - Results are noticed immediately and overall beard darkness gets better after several uses if done as a daily routine. Disadvantages- very messy stains sinks , bathroom floor and finger nails and lips.

Control GX Light Shades does exactly what it promises -- delivers partial and gradual elimination of gray hair. Ideal if your hair color is anything other than black -- brown, light brown, blonde -- works invisibly with all these hair colors. Looks natural, and is so easy to use. The shampoo component is really good too, one of my favorite personal care products. Highly recommended.

me encantan este marca y realmente no es que reduce las canas, te tiñe progresivamente mientras lo usas.

It does reduce the appearance of gray. However, the non-gray hairs seem to take up significantly more of the dye. The white hairs will turn into a dull, darker gray while the brown hairs turn black. This has a blending effect. But the beard overall looks significantly darker. It is very noticable. You will get the question, "Did you dye your beard, it looks darker". I don't understand why they market this product as being for all hair colors. It definitely is not. They need lighter versions. If it was a brown dye that didn't turn black it would be a good product.
