Encourage Hair Nourishment The Hair Strength Shampoo helps reduce abundant sebum (oil), lowering greasy hair; provides necessary nutrients and vitamins; and improves the overall strength of hair. It moisturises the scalp and hair to counter dry skin, all while leaving a pleasant eucalyptus aroma. The Hair Recovery Conditioner is a perfect follow-up supplement to the Hair Strength Shampoo. It crafts a lipid-based protective layer to replace stripped natural oils, while repairing deep into damaged hair strands.
