Alterna is an eco-conscious American haircare brand much beloved by salon stylists who like its innovative approach and head-turning results.

The products are based around natural ingredients including caviar, hemp, bamboo and kendi oil. And they stay well away from baddies such as sulfates, parabens, gluten, paraffin and petrolatum.

Alterna combines its natural ingredients with technological advances such as Enzymetherapy – an enzyme delivery system enabling the absorption of essential ingredients for superior keratin production, and Color Hold, a patented technology protecting hair from colour fade and wash out. Together, they make for visible, lasting improvements to your locks, whether you're concerned about ageing hair, frizz, brittleness, or sun damage.
