First Things First

They look like soaps, but it's shampoo in solid form. Our concentrated formulas subtract water from the equation. Single-use items are one of the biggest offenders of waste in the haircare industry. Instead, we add only the essentials, you add water.

A little goes a long way too. Once activated with water, your bar will create a rich sudzy lather that cleanses your scalp and hair without leaving it stripped or heavy.

How to Use Your Bar

Simple. Easy. No complicated routine needed.

Wet hair in shower

1. Fully Wet Your Hair

Your bar activates with water, so make sure your hair is thoroughly soaked before using it.

Applying shampoo bar to hair

2. Glide the Bar on Wet Hair

Rub the bar directly onto your scalp a few times. Since it's concentrated, you don’t need a lot.

Massaging shampoo into scalp

3. Massage & Lather

Use your fingertips to work the lather into your scalp like a traditional shampoo. Lets the sudz naturally flow to your ends.

Rinsing hair in shower

4. Rinse Thoroughly

Rinse well and follow with our conditioner bar to replenish lost moisture and make detangling easier for soft, defined curls.

Using Your Conditioner Bar

Conditioner bars work best on very wet hair. Glide the bar from your mid-lengths to your ends. Press lightly for fine hair. Apply ears down for oily hair, avoiding your scalp.

OTHER WAYS TO USE: Use it as a leave-in, after-swimming for easy detangling, or to refresh your curls by applying to lightly misted hair for soft definition without heavy buildup.

Using conditioner bar

Use your fingertips or a wide tooth comb to distribute the product evenly through your curls. Let it sit for a minute or two before rinsing.

Using conditioner bar

To dry curly hair without causing frizz, never rub your hair with a traditional terrycloth towel, instead, use a microfiber towel. Gently squeeze out excess water in a scrunching motion, or use the "plopping" method to set your curls and remove moisture quickly

Using conditioner bar

Microfiber creates a smooth, frictionless barrier that let your curls pop. Then let your curls air dry or diffuse.
