18 tommers Clip-in Hair Extensions | Tagged: Mahogany Red (#99J)

18 inch extensions measure approximately 45cm in length and typically sit around mid-back on most people. The exact placement can vary slightly depending on your height, torso length and where you apply the extensions. On petite frames, they may fall a little lower, while on taller individuals they can sit slightly higher on the back. This length is popular because it looks noticeably longer without feeling too dramatic, making it easy to wear both casually and for special occasions.

The best weight depends on your natural hair thickness and how full you want your hair to look. If you have fine hair, 120g-160g usually provides a natural boost without feeling heavy. Medium hair types often suit 180g-200g for balanced volume, while thick hair or those wanting bold fullness may prefer 240g-300g sets. Choosing the right weight ensures your extensions blend well and feel comfortable throughout the day.

Both options offer excellent coverage – the choice comes down to how much volume you want and how discreet you want the wefts to feel.
