I've been using this shampoo 2–3 times a week on both my hair and beard for over 4 years, usually leaving it in for about 2 minutes (until my Sonic toothbrush stops). I'm very happy with the results — my wife constantly compliments how natural it looks, unlike the solid “helmet” effect I used to get from traditional hair dye. I just counted and realized I've ordered 25 bottles so far, mostly through subscription! Only once did I have a staining issue — totally my fault. I had cleaned up a mess from one of my dogs with Clorox wipes (no gloves), then immediately showered. My hands were stripped of oils, so the shampoo stained my fingers. Since then, I’ve been more careful, and it hasn’t happened again. Highly recommended for a natural, gradual color refresh. Read more

Gostei da qualidade do produto, que atendeu às minhas expectativas. O produto é muito caro quando vendido no Brasil pela Amazon, comparado ao preço da Amazon dos Estados Unidos. Read more

You have to wait at least 5 minutes before to rince your hair and rince the shower after to avoid dark trace on the walls or the floor of the shower/bath tube. Read more

I've been using this product for years now and frankly I think it is the most natural looking and best way to get the grey out and it's super affordable. I use it on my hair and beard and it works great. That said this product is not as easy to use as the manufacturer would have you believe. Here are some tips that I have picked up over the years. 1. If you tolerate it, I like to put it in my hair and beard and let it sit for a while (about 30 minutes) before rinsing it off. I feel this gets you to the desired color faster and it lasts longer. Be careful to only get the shampoo on the intended area as your skin may stain and its hard to clean off. 2. This stuff stains everything. I keep the the tube in a freezer bag (even in the shower) as it always leaks a bit from the cap and it will stain anything the tube is sitting on. Do not leave a tube to sit in the shower or on a counter without it being in a bag. 3. Wear surgical gloves or remember to wash your hands quickly especially around the fingernails. If this stuff gets under your fingernails its hard to get out and looks terrible. 4. Don't shake your head vigorously in the shower while rinsing. Just let the water flow over your head and agitate it mildly, otherwise the drops will get all over your shower curtain and you guessed it, stain it. 5. Use a dedicated old towel you don't care about for drying your hair after using the product. I bought a black towel on Amazon and I only use that when drying my hair after using this. Remember to wash that towel alone and not with other clothes. 6. If you do get drops on the bathroom counter of shower, clean it up quickly. If you miss a spot and the stain won't come up easily because its been sitting for a while, try a magic eraser. Again, I love the product, but to keep the dye just in your hair and not anywhere else you don't want it is a process. I hope you found these tips helpful Read more

I've been using ControlGX shampoo for a few weeks now, and I'm thrilled with the results! Initially, I used it daily for five days straight, and then switched to every other day. The reduction in grey hair is truly noticeable, and I'm loving it! My hair feels healthier, and the gradual change looks completely natural. Definitely a game-changer for anyone looking to manage their grey without drastic measures. Highly recommend giving it a try! Read more

Not effective Read more

Don’t get fooled by the positive reviews. It’s a trap. I have been using it for a while no change at all. Nothing happens. Total waste of money Read more

And you can apply it once a week or less. Read more

Did what it should do Read more

I have been using this product for last two years. It does not give any allergic reaction and is safe to apply on the scalp. Apply on hair and keep is for half an hour, then rinse. It provides a perfect brown black rich color. Highly recommended Read more

Doesn't work. Read more

This is literally a game changer. SO simple to use and you get results within 2-3 applications. I was pretty gray all over and 3 applications in, I'm back to dark brown. As other reviewers have said, you MUST leave it on for at least 10 minutes. What I do is shower up, put it on and then go and send a few emails - come back and wash it off and hey presto - gray gone! JFM basically have me as a customer now for life! Read more
