Hair Guru London Natural Hair Thickening Fibres 28g

Thicker-Looking Hair, Shade-Matched To You

Hair Guru London Natural Hair Thickening Fibres are a 28 g shaker bottle of fine cotton fibres, coloured with mineral pigment and offered in 14 shades. Shaken over thinning areas, the fibres take hold of the hair you already have and build the look of fuller, denser coverage across the crown, parting, temples and hairline. There are just two ingredients, the formula is vegan and cruelty-free, and it suits men and women with any hair type.

How The Fibres Work

Each fibre carries a natural static charge that draws it to existing strands, including the very fine ones that are easy to overlook. As the fibres settle, they wrap around those strands and fill the gaps between them, so the scalp shows through less and hair appears thicker from root to tip. They are a cosmetic finish rather than a treatment, which means the effect is instant and simply washes away with your next shampoo.

Finding Your Shade

Choose the shade closest to your roots rather than your lengths, as that is where the fibres sit. If you find yourself between two colours, the darker of the pair usually gives the more natural finish, and two shades can be blended together for a fully personal match. The range runs from Black and the browns through to blondes, greys, White and two auburn tones, so there is a starting point for almost every colouring.

Styling

Use the fibres whenever you want extra density: as part of a daily routine, before a special occasion, or for photographs where a parting or crown can look sparse under bright light. For neat, controlled coverage along the hairline and temples, attach the Hair Guru London Easy Apply Fibre Pump to the bottle, and finish with Hair Guru London Hair Fibre Locking Spray to help the fibres hold in place throughout the day. Both are sold separately.

How To Use

Start with clean, completely dry hair, styled as you would normally wear it. Hold the bottle a little above the area you want to cover and shake or tap the fibres over it, building up gradually rather than all at once. Pat the area lightly with your fingertips to settle the fibres into your hair, then mist with Locking Spray to set them. Finish your style as usual.

Frequently Asked Questions

How do hair thickening fibres work?
The fibres are statically charged, so they cling to your existing hair and fill the spaces between strands. This makes hair look thicker and reduces how much scalp shows through. They are cosmetic and do not affect hair growth.

Which shade should I choose?
Match the shade to your root colour. If you are unsure between two, the darker option generally looks more natural, and you can mix two shades to create your own blend.

Do I need existing hair for the fibres to work?
Yes. The fibres bond to the hair that is already there, including very fine strands, so they are best suited to areas where hair has thinned rather than skin with no hair at all.

How can I make the fibres last all day?
Apply them to dry, styled hair, pat them in gently, then set them with Hair Guru London Hair Fibre Locking Spray, which is designed to hold the fibres in place.

Are the fibres suitable for women as well as men?
Yes. They work on all hair types for both men and women, whether you want to fill a wider parting, a thinning crown or a receding hairline.

What are the fibres made from?
Just two ingredients: natural cotton fibre and a mineral-based colourant made from natural iron oxide. The formula is vegan and cruelty-free.
