Which gives a more natural look?

Control GX, because it reduces grey slowly over washes instead of applying a solid black dye. COSYAGE gives a darker, more uniform result in one wash.

COSYAGE. It is a 5-minute dye shampoo. Control GX generally takes 2 to 4 weeks of regular use to reach your target level.

Is Control GX worth it over COSYAGE?

If you want subtle grey reduction and a lower price, yes: $10.97 at Walmart versus $15.99 at Amazon as of November 7, 2026. If you want full black coverage fast, COSYAGE is the better fit.

How long does each last?

Control GX is good for 3 months once opened, and maintenance use is about 3 to 4 times a week. COSYAGE is demi-permanent, so color fades gradually and needs reapplying.

Can I use Control GX every day?

Yes. Use it daily at first, then rotate with your usual shampoo once you like the result.

Does COSYAGE work on a full beard?

It is marketed for beard and mustache grooming and grey coverage, so yes, but it is a single black shade with no gradual control.
