Dull, weak hair? Hair Caviar to the rescue! Honestly, these tiny purple capsules contain a potent serum. First I feed my hair. Then I feed my plants (the capsules are biodegradable and nutrient dense…if you dissolve them in water, the water can be used to feed your plants). Btw - all of their products are clean, vegan and formulated without parabens, SLS/SLES* sulfates and other harsh chemicals. 🙌
