Inside Full Crown.
Full Crown is our most advanced scalp treatment. A complex of five bio-engineered peptides (sh-polypeptides and sh-oligopeptides) works alongside saw palmetto, rosemary and eucalyptus to nourish the scalp and support the look of fuller, denser hair.
Arginine, soy and wheat germ extracts and skullcap root add amino acid and botanical support. The formula is weightless and non-greasy, so a daily scalp massage fits into any routine without affecting your style.
“Crowning glory is a daily ritual.”

Full Crown, answered.
How long does it take to see fuller-looking hair?
Hair grows in cycles, so give Full Crown at least 3 months of consistent daily use. Many people take progress photos every 4 weeks to track the change.
Can I use Full Crown with Rosemary Root?
Yes. Use Full Crown in the morning and Rosemary Root in the evening, or alternate days, for a peptide-plus-botanical ritual.
Does it contain allergens?
It contains soybean and wheat germ extracts. Avoid if you have a soy or wheat allergy and patch test before first use.
