Keratin & Macadamia Oil for Stronger, Smoother Hair

This dual-action formula combines:

Keratin – A protein naturally found in hair that helps support strength, improve elasticity and reduce the appearance of breakage.

Macadamia Oil – A lightweight, nutrient-rich oil that helps restore softness, enhance shine and smooth the hair cuticle.

Together, they work to improve the look and feel of stressed or over-processed hair while maintaining natural movement.

Ideal for Dry, Damaged & Frizz-Prone Hair

Bio Spa Keratin & Macadamia Oil Hair Shampoo is particularly suited to:

✔ Dry or dehydrated hair
✔ Heat-damaged hair
✔ Colour-treated or chemically treated hair
✔ Frizz-prone textures
✔ Hair exposed to sun, salt water and harsh Australian climates

The formula helps cleanse impurities while supporting hydration — essential for maintaining smoothness in Australian weather conditions.

Gentle Cleansing Without Stripping Natural Oils

Unlike harsh shampoos that can leave hair brittle or tight, this shampoo is designed to cleanse while helping preserve moisture balance. The result is hair that feels clean yet conditioned, with improved softness and manageability.

For best results, follow with a complementary conditioner or treatment mask to enhance smoothing benefits.
