Humectant

Humectants are ingredients that have the ability to draw moisture from the air into the hair and hold onto it. They can help maintain hydration levels in the hair, preventing dryness and brittleness.

Humectants attract water molecules from the environment or from deeper layers of the hair and scalp. This ability to pull moisture helps keep hair hydrated. Once moisture is attracted to the hair, humectants help to lock it in, preventing it from evaporating. This can lead to softer, smoother hair.

Humectants help keep hair hydrated, which is essential for maintaining its health, elasticity, and overall appearance. By attracting moisture, humectants can help reduce frizz and flyaways, leading to smoother and more manageable hair. Regular use of products containing humectants can result in softer, shinier, and healthier-looking hair. Humectants can also benefit the scalp by keeping it hydrated, which can alleviate dryness and irritation.

The effectiveness of humectants can be influenced by the humidity in the environment. In high humidity, humectants can pull moisture from the air, which is beneficial. However, in low-humidity environments, they may draw moisture from the hair, potentially leading to dryness. It's important to balance humectants with occlusives (ingredients that create a barrier to lock in moisture) in such conditions.

Some widely used humectants in hair care include glycerin, aloe vera, honey, propylene glycol, and sorbitol.
