I have used this product for 30+ years! I use this product every two - three weeks to keep the most natural-looking color. I try to apply to only new growth hair that is grey so that the ends of the hair do not build up too much color, which looks unnatural.

Just use as you would your regular shampoo until you like what you see (generally within 2-4 weeks), then use it a few times a week to maintain. Leave the shampoo in your hair for 1-2 minutes while you shower. To see more about using Control GX® click here.

On average, shampoos and conditioners can show results as soon as you use them. But other products - such as hair masks and serums - may not have noticeable effects until a few weeks or months later.

One to two months is the average amount of time an effective, drug-free hair growth shampoo should begin to work, but effective is the key word. A high-quality shampoo only works as well as the mix of active ingredients it contains. The higher the concentration of key active ingredients, the faster you'll get results.
