How our four lengths compare

12 inch · 90g · £109Shorter and subtle. Sits at the shoulders. Best if your own hair is shoulder length or you want volume more than length. Also available as a 45g Lightweight for fine hair (£89).
14 inch · 100g · £129Just below the shoulders. The most versatile length: noticeable extra length and volume without looking dramatic.
16 inch · 110g · £149Mid-back. A clear extension that still moves naturally. Good if your own hair already passes your shoulders.
18 inch · 120g · £159Lower back to waist. Full-glam length for events, bridal and anyone who wants the longest natural-looking result.

Who the 18 inch suits

The 18 inch is our longest and fullest piece: 120g of Remy hair that falls to the lower back or waist. Choose it for bridal, events, or if long hair is simply your look. Because it is the heaviest, it suits medium to thick natural hair best; on fine hair we would suggest the 14 or 16 inch so the wire stays hidden and comfortable.

Styling tips at 18 inches

Long extensions look most natural with some movement. Waves, a low ponytail or a half-up style all work. Brush from the ends upward, store the piece hanging or in its bag, and it will keep its shine for months of wear.

Questions about 18 inch extensions

How is the 18 inch length measured?

From the wire down to the ends of the hair, with the hair straight. Worn on the head it sits at the lower back or waist. If you are between two lengths, order the shorter one: length exchanges are free.

Is 120g enough hair to look full?

Yes. Our wefts are wider than most on the market and the weight is spread across the whole back of the head, so 120g reads as a full head of hair rather than a thin panel. Customers with very fine hair often prefer the Lightweight 12 inch at 45g.

Can I curl, straighten and wash it?

Yes. It is 100% Remy human hair. Use a heat protectant, keep tools at or below 180°C, wash every 8 to 10 wears and use a hair oil on the ends.

How do I get the colour right?

Send us a photo in natural light through our free colour match. We recommend the shade; if it isn't right when it arrives, colour exchanges are free.
