Apply to the Scalp: Section your hair and massage the warm product directly into your scalp using the pads of your fingers (avoid using your nails) for 2 to 5 minutes to boost circulation. [1, 2]

Distribute Through the Lengths: Work the mask or oil down the mid-lengths and focus heavily on your ends, where hair is oldest and most damaged. You can use a "praying hands" motion or a wide-tooth comb to spread it evenly. [1, 2, 3]

Processing Time:Standard Mask/Pre-Poo: Cover your hair with a plastic cap or shower cap and leave it on for 30 minutes.Deep Overnight Treatment: For thick, coarse, or very dry/damaged hair, you can leave it on overnight (cover your pillow with an old towel or wear a silk bonnet/scarf).(Note: If you have fine or straight hair, keep it to 10–20 minutes so it doesn't weigh your hair down). 

If you stop using the oil, your hair stops growing more. It stays the way it was on the day you stopped. When you start using it again, your hair keeps growing from there.
