No matter how i shake, the end of the tube is alway just dark brown (beige out of a new tube). is this going to work the same?

I've been using Control GX for a couple of years. This product uses a chemical reaction that depends on oxygen to activate the dye. Sealed up in the tube it's a beige color. Once you squeeze it out and apply, it begins to react with the oxygen in the air and darken over the course of 5-10 minutes. You'll even notice a further small amount of color change over the 24 hours after you've rinsed it out and dried your hair as oxygen continues to react with the dye bonded to your hair. The key to minimize the color change in the tube is to minimize the exposure to oxygen while it is stored for weeks while you use it. If you are using it say 4 times per week you may go through a tube in a couple of weeks and that will limit the amount of time it will sit in the tube reacting to oxygen. Personally, I have a medium brown natural hair color. After getting my hair color where I wanted it, I only use Control GX once or twice a week to maintain the look I want. So a tube will last me 4-6 weeks. In that time, it will oxidize and turn partially black. But there is something you can do to minimize that. When you finishing applying and you're waiting for the dye to work, go back and pop open the tube then squeeze it so that the goop inside is just about to come out. Now close the cover and make sure it snaps shut. That will expel 99% of the oxygen from the now partially empty tube and seal it as well as possible. Store it standing up vertically so the stuff inside forms a seal against the top (bottom when stored). If you don't do this, all that space inside the tube that used to be filled with Control GX ends up filled with oxygen and the chemical reaction will take place. With that said, I use it whether or not is is oxidized and it still seems to have an effect even if it is partially oxidized.

Will the chlorine in a swimming pool or hot tub bleach out the product or cause it to run off?

So you have a couple of questions here. Let me unpack the easiest one first. No LOL, the product doesn't run under any circumstance. Once you've rinsed off the Control GX and you're out of the shower, the dye is set in your hair until you cut that hair off. You won't end up looking like Rudy Guiliani with shoe polish in your hair. The dye chemically bonds with the keratin of your hair. And nothing short of another chemical is going to break those bonds. Which brings us to your second question. Will pool chlorine affect the color of hair dye. I have an in ground pool with a chlorine system. The short answer is yes, chlorine is a highly reactive chemical. That's why it's used to control bacteria in a pool in low concentrations and get fabrics white in the laundry at higher concentrations. And as we all know, chlorine will absolutely destroy fabric dyes in a washing machine. Wanna ruin a pair of black jeans? Throw em in the wash with some chlorine bleach. It's the same with hair dye. Chlorine will absolutely react with anything it comes in contact with. But.....if you're using a pool with proper pH balance and chlorine levels, the effect is very minimal in my experience. I use my pool several times a week from June - September and I really don't notice much impact. If you're in and out of the pool for a couple of hours and then go take a shower, you won't notice much impact if any. If you're in the pool 4 hours a day and leave the chlorine in your hair for another 4 hours before you shampoo, you'll probably see more impact. But that's true of any dye on anything from hair to clothing. UV radiation from sunlight will also have an impact. So pool water + UV light for 8 hours will have an even greater impact. But even then, the effect is gradual. Hope that helps.

if you leave it in longer will it work quicker or just get darker

Both! Basically leaving it in longer darkens the hair faster. I use anywhere from 5-12 minutes depending how much color I want at any given application. If you keep using it more often and leaving it in longer, it will get darker and darker. Less often and less time will get you a "salt & pepper" look. And no it doesn't "Fade". It's basically a permanent dye that will be there until your hair grows out and you cut it. The reason you need to keep applying is that your hair keeps growing and exposing new gray hair.

Is this a hair dye that you will have to use forever?

Unless your body begins to change itself back to a younger version of you that no be longer has grey hair than the answer is, Yes or at least as long as you like not being grey

This stuff is the BOMB!

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!

The most non allergic hair dye

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

Thanks for timely shipped & delivery. This is what exactly I wanted as I have been using it for last many years. This is excellent product and I recommend for men who want to have salt & grey mixed or no grey hairs.

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
