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.
