The 5 reasons, one by one ↓

1
Reason No. 1

The salon bill keeps coming back, just like the roots

A root touch up plus tip can run $100 or more. A few weeks later, that silver line is back at your part.

One $56.99 bottle gives you about 10 to 15 washes. That works out to under $4 a wash.

Each wash keeps your color for about 2 to 4 weeks. So one bottle can last you for months, right at home.

Want two shades, or one to share? Buy 2 Get 1 Free gives you 3 bottles for $113.99. Each bottle in a bundle can be a different shade.

Reason No. 2

Four things you won't find in the bottle

Remember the sharp smell on box dye day? Cozylea is made without ammonia.

It is also made without PPD, parabens or phthalates. Lab tests in South Korea show it suits sensitive scalps.

The same lab tests show it restores pigment. It is cruelty free, too.

Skip it if your scalp is sore, broken or irritated right now.

Reason No. 3

Those 15 minutes care for your hair, too

Worried about your hair during those 15 minutes? While the color sets, six plants from old hair rituals add care.

Panthenol, glycerin and wheat protein are in there, too. The plants bring the care. The formula brings the color.

Reason No. 4

Soft, even color that blends right in

The big worry is simple. Will people be able to tell? Pick the shade your hair was before the gray came in.

Lather it on dry hair, from roots to ends, for even color. The longer you leave it on, the deeper the color gets.

Trying it the first time? Start with 5 minutes and check the mirror. Stubborn white at your temples? Leave it on up to 25 minutes.

5 minA soft, gradual blend
15 minEven color on gray roots
25 minRicher color that lasts longer

Color lasts about 2 to 4 weeks. When roots peek out, patch test, then wash again.

Questions women ask before they switch

My hair is already dry. Will this make it worse?

It is made without ammonia or PPD. It also has panthenol and glycerin for softness. Not happy? You have 30 days to get your money back.

What if my gray turns orange, or the shade looks off?

Pick the shade your hair was before the gray. Start with 5 minutes, then go longer next time. In a bundle, you can mix shades. And the 30 day promise still covers you.

Does it leave stains on skin or the sink?

It is made not to stain. Wipe any drip off your skin within 5 minutes.

Do I really need a patch test every time?

Yes, every single time. Dab a little behind your ear 48 hours before use. Never use it on brows, lashes, or an irritated or broken scalp.

How many weeks will my color last?

About 2 to 4 weeks, depending on how often you wash. One bottle gives about 10 to 15 washes.
