Dry ends can ruin an otherwise perfect hair day. They make your hair look lifeless, feel rough, and break more easily. But what causes dryness—and more importantly, how can you fix it?

What Types of Hair Need Extra Moisture?

Naturally Curly or Wavy Hair

Curly hair is naturally more porous, which means it's more prone to losing moisture. The oval shape of curly hair doesn’t retain hydration as well as the round structure of straight hair. Plus, the hair’s texture makes it harder for natural oils to travel down the strands, often resulting in dryness and frizz.

Gray or Graying Hair

As hair turns gray, it loses melanin—changing its structure and often becoming coarser and more porous. At the same time, your scalp’s oil production decreases, leading to a drop in natural moisture and shine.

Fine, Untreated, Easily Static Hair

Static is often a sign of dryness and lack of moisture balance. Dry hair builds up static electricity more easily, especially in dry indoor air or during winter months. Hydrating products help restore balance and reduce frizz and flyaways.

Chemically Treated or Bleached Hair

Chemical treatments like bleaching lift the hair cuticle and can damage the inner structure, making hair more porous and vulnerable to moisture loss. Regular deep hydration is key to restoring elasticity and maintaining strength.

Extra Tips for Managing Dry Ends

- Trim regularly: Split ends don’t stop at the tips—they can split higher up the shaft and even cause breakage near the root if left unchecked.

- Avoid unnecessary heat: Minimize the use of hot tools, and always apply a heat protectant like the Professional Bio-Molecule Repair®Serum, which not only guards against heat but also repairs the hair’s structure.

- Be gentle when drying: Swap your regular towel for a microfiber towel—or even a soft cotton t-shirt—to reduce friction and moisture loss.
