How to oil low-porosity hair

Warm the oil slightly and apply a light layer to damp lengths, then add heat (a warm towel or shower cap) for 20–30 minutes so it can penetrate. Keep it pre-wash, not overnight.

Pro tip: Heat is your friend: deep-condition under a warm towel or steam to lift the cuticle so moisture gets in.
