Primary Scalp and Hair Functions:

• Scalp Exfoliation: The physical salt particles act as a "scaler," loosening old keratin and dead skin to unclog pores.
• Oil and Sebum Control: Sea salt has natural absorbent properties that regulate overactive sebaceous glands, making it highly effective for those with oily or greasy hair.
• Volumizing and Texturizing: Salt slightly swells the hair cuticle and increases friction between strands, providing an "effortless beachy look" with more body and lift at the roots.
• Mineral Infusion: Many formulas, such as GROWUS Sea Salt Therapy Shampoo, use mineral-rich salts (like Dead Sea or Red Sea salt) to deliver magnesium, calcium, and potassium directly to the follicles to support hair strength.
• Anti-Dandruff and Anti-Itch: The antifungal and antibacterial properties of sea salt help reduce the moisture and fungi that contribute to dandruff, while also soothing itchy or irritated scalps. 

Recommended Usage and Best Practices:

1. Preparation: Thoroughly wet your hair and scalp with warm water.
2. Application: Apply a quarter-sized amount directly to the scalp and massage for 2–3 minutes to allow the scrub particles to work.
3. Absorption: For maximum benefit, leave the foam on for 1 minute to let minerals penetrate.
4. Frequency: It is typically used as a treatment 2–3 times per week or even once a month for a "detox," rather than as a daily shampoo, unless you have extremely oily hair.
5. Post-Care: Always follow with a deep conditioning treatment or nourishing essence, as salt can leave hair feeling stiff or "straw-like" if not properly rehydrated.
