Hair bonding glue or adhesive is the commonly used product to seal the ends of hair extensions. This type of adhesive is specifically designed for securely attaching extensions to natural hair, ensuring that they stay in place for an extended period of time. The glue forms a strong bond that can withstand day-to-day wear and styling, which is crucial for maintaining the integrity of hair extensions.

Using the right adhesive also ensures a more natural appearance and helps to prevent tangling and shedding of the extensions. It's particularly important to choose a product that is formulated for hair to avoid damaging the natural hair or causing irritation to the scalp.

Other products such as hair spray, wax, or conditioner do not provide the necessary strength and lasting hold required to effectively seal hair extensions. Hair spray can add hold for styling but does not bond extensions; wax may provide some texture but is not suitable for attachment; and conditioner is meant for moisturizing and does not offer any bonding properties at all. Therefore, the use of hair bonding glue or adhesive is the most effective and appropriate choice for sealing the ends of hair extensions.
