Delivery: £3.49 for the first item, then £0.15 for each additional item.

Add deep black length and fuller-looking results with our #1 Jet Black 18 Inch 0.5g Micro-Loop Hair Extensions. Made from Chinese Remy human hair, each individual strand comes with a loop and Micro Ring already attached, making the extensions ready for professional Micro-Loop fitting.

Each strand weighs approximately 0.5g, providing approximately 12.5g of hair across 25 strands. At approximately 18 inches / 46cm in length, this option provides noticeably more length than the 14-inch range while retaining the lighter 0.5g individual-strand format.

#1 Jet Black is the deepest true-black shade within our colour range, making it particularly suited to hair with a strong, distinctly black appearance.

What Are 0.5g Micro-Loop Hair Extensions?

Micro-Loop hair extensions are individual human hair strands supplied with their own pre-attached loop and Micro Ring. Because the fitting attachment is already positioned on each strand, there is no need to add a separate Micro Ring before application.

During fitting, a small section of natural hair is passed through the pre-attached loop. Pulling the loop guides the natural hair through the attached Micro Ring before the ring is positioned and secured using suitable smooth-jaw extension pliers.

The Micro-Loop fitting method does not require heat, glue or bonding adhesive. Correct section size, ring positioning and tension remain important for a secure and comfortable application.

At approximately 0.5g per strand, the extension hair is distributed across multiple individual attachment points. The appropriate quantity and placement should be selected according to the density and condition of the natural hair and the desired finished result.

Professional consultation and fitting are recommended to determine the appropriate quantity and placement for the natural hair.

How Many 0.5g Micro-Loop Strands Do I Need?

These extensions are supplied in quantities of 25 strands. For our 0.5g Micro-Loop range, the recommended guide is approximately 150–200 strands (6–8 bundles) for a full-head application and around 100–150 strands (4–6 bundles) for a half-head application.

The exact quantity required will depend on your natural hair thickness, density, existing length and the amount of additional length or volume you want to achieve. We recommend discussing the required quantity with your hairstylist before ordering.

Important quantity information: The price shown is for 25 individual 0.5g strands, providing approximately 12.5g of hair in total. Product imagery may show packets containing four bundles or more, so please use the stated strand quantity when calculating how much hair you require.

Micro-Loop Fitting Tools

As the loop and Micro Ring are already attached to each extension strand, fitting primarily requires suitable professional extension pliers. Smooth-jaw pliers are used to secure the Micro Ring once the natural hair has been guided through the pre-attached loop.

Micro-Loop Hair Extension Fitting

A small section of natural hair is passed through the pre-attached loop. The loop is then pulled to guide the natural hair into the attached Micro Ring. Once correctly positioned, the ring is secured using suitable smooth-jaw professional extension pliers.

No heat or glue is required during this fitting process. Correct section size and placement should be selected according to the density and condition of the natural hair.

Micro-Loop Hair Extension Application

Micro-Loop extensions help streamline individual-strand application because the loop and Micro Ring are already attached to each extension. Correct strand placement, section size and ring positioning remain important throughout professional fitting.

Micro-Loop Hair Extension Removal

Micro-Loop extensions should be removed carefully by reopening the attached Micro Ring with suitable removal pliers before gently releasing the extension strand from the natural hair.

The Micro Ring should not be pulled or forced from the natural hair while closed. Professional removal is recommended to help minimise unnecessary tension around the fitted areas.

View our Micro-Loop Hair Extension Fitting & Removal Guide for further guidance.

Micro-Loop Hair Extension Aftercare

With appropriate fitting, care and maintenance, these extensions can be worn for approximately 2–3 months. The human hair can be cut, washed and styled, including curling and straightening, but correct care of both the extension hair and Micro Ring attachment areas is important throughout wear.

Always use a suitable heat-protection product when using heated styling tools on the extension hair. Avoid applying direct heat to the Micro Rings or attachment areas.

Oils, conditioners and heavy styling products should also be kept away from the fitted points, as these may contribute to slippage. Brush the extensions carefully while supporting the attachment areas.

Follow our Hair Extension Aftercare Guide for full maintenance information.

Choosing #1 Jet Black

#1 Jet Black is the deepest true-black shade within our colour range. It has a strong, distinctly black appearance and is intended for hair sitting at the darkest end of the colour spectrum.

Compared with #1B Off Black, #1 Jet Black is deeper and more intense. #1B provides a slightly softer black appearance and may reveal subtle brunette tones in natural daylight, while #1 remains more distinctly true black.

Compared with #2 Dark Brown, #1 Jet Black contains considerably greater black depth. #2 moves clearly into a deep brunette appearance rather than a true-black result.

If your hair remains distinctly black in different lighting conditions, #1 Jet Black may provide the closer match. If it reveals noticeable brunette or brown tones in daylight, #1B Off Black or #2 Dark Brown may be worth comparing.

For the best colour comparison, check the extensions against the mid-lengths and ends of your natural hair in good natural daylight rather than matching only against the roots.
