Frequently asked

Common questions.

Should I apply hair oil to wet or dry hair?

Wet for sealing in moisture; dry for shine and frizz control. Most kits benefit from one of each application.

Will hair oil cause scalp build-up?

Silicone-heavy oils, yes. Pure plant oils, no. Apply oil mid-shaft to ends only; avoid scalp.

How much hair oil should I use?

Pea-sized for shoulder-length, 2 peas for longer hair. Most users apply 4× too much, then complain hair looks greasy.

Hair oil before or after styling?

Before for protection during heat styling; after for shine. Both jobs at once doesn't work, pick one.
