Help & FAQ

Visible shine and softer hair from the first use. With regular use, expect smoother, more manageable hair that looks and feels healthier over time.
Apply to damp or dry hair before your workout. Distribute evenly from the scalp to the tips, then train as usual. Afterwards, wash your hair as normal or leave it in as a slick back and go about your day. You can leave it in all day. Not training today? Apply it anyway and leave it in for at least 10 minutes.
4+ uses per sachet, depending on your hair type, length and thickness.
Think of it like training, consistency builds results! Use it 2-3 times a week for best results, ideally on your training days. More active? You can use it every session.
