Strength: Nylon thread is known for its high tensile strength, meaning it can withstand tension and hold the hair extensions firmly in place without easily breaking.

Lightweight: Nylon thread is relatively lightweight, which is crucial for hair extensions as it doesn't add unnecessary weight or strain to the natural hair.

Resistance to Moisture: Nylon is hydrophobic, meaning it repels water. This resistance to moisture is beneficial as it helps the thread maintain its integrity and prevents weakening due to water exposure.

Non-Biodegradable: Nylon is a synthetic material and non-biodegradable, meaning it doesn't break down naturally over time. This ensures the longevity of the hair extensions, and they can last for an extended period with proper care.

Flexibility: Nylon thread is flexible, making it easy for stylists to work with and create various attachment patterns that look natural and blend seamlessly with the client's hair.

Hypoallergenic: Nylon thread is generally considered safe for most people and is less likely to cause allergic reactions or irritate the scalp.
