Frequently Asked Questions

What are Hair Guru London hair thickening fibres, and how do they work? 


Hair Guru London hair thickening fibres are advanced cosmetic products designed to instantly improve the appearance of thinning hair. Our fibres are made from natural materials and attach to the natural static energy of your own hair, creating a thicker and fuller look. The fibres blend seamlessly with your hair, making it appear thicker and concealing areas with less hair density.

Are Hair Guru London hair fibres suitable for both men and women?

Yes, our hair fibres are formulated to be suitable for both men and women. Whether you're dealing with hair thinning or simply want to enhance the volume and density of your hair, Hair Guru London fibres are a versatile and effective solution.

How do I choose the right shade to match my hair colour?

Match to your root colour, not your ends. If you’re between two shades, go darker or mix both for a perfect match. We offer 14 natural shades - email info@hairgurulondon.com or DM us for a free 24-hour colour match.

Can I use Hair Guru London fibres with other hair styling products?

Yes, you can use Hair Guru London hair fibres in conjunction with other hair styling products such as gels, mousses, or hair sprays. Apply our fibres after styling products (using the pump), and then use our Hair Guru London Locking Spray to set the fibres in place for a long-lasting hold.

How long does a single application of hair fibres last?

That depends on coverage:

-Light coverage (partings or temples): 6–10 weeks per 28 g bottle

-Full coverage (top or crown): around 3– weeks

-The 100 g refill pouch offers the best value if you use it regularly.

 

Will they survive sweat, wind and light rain?

Yes, especially when set with our Locking Spray. Gym, wind and drizzle are fine. After heavy rain or swimming, pat dry and touch up if needed.

Do they stain pillows or clothes?

Applied correctly and set with Locking Spray, transfer is minimal. Let any styling products dry first and avoid over-applying around the hairline. If you do get transfer on fabric, it brushes off dry; wash as normal.

How do you attach the Easy Apply Pump

1. Place the fibre container on a flat surface and hold steady with one hand

 

2. With the other hand, hold either side of the salt shaker end and give it a good pull away from the container (be careful not to spill the fibres)

 

3. The salt shaker end pulls off rather than screws

 

4. Once removed, screw on the pump
