How to Choose Clip-In Hair Extensions That Match Your Hair Colour
A perfect colour match is key to a seamless blend. Hereโs how to get it right:
1. Compare in natural daylight
Indoor lighting can distort tones. Always check swatches or your natural hair in the daylight.
2. Match to the ends - not the roots
Your mid-lengths and ends determine the visible blend.
3. Ask an expert (free)
Send us photos - front, back and sides in natural light and our team will recommend your best-matched shade instantly.
4. Consider multi-tonal shades
Hair Rehab London clip-ins feature multi-dimensional tones so they blend beautifully with natural colour, highlights, balayage, and lowlights.

How to Apply Clip-In Hair Extensions (For Beginners) โ Step-By-Step
Whether youโve never worn clip-ins before or just want a refresher, follow this easy beginner-friendly guide.
Step 1: Prep the hair
Brush through your natural hair and create a clean, smooth base. Applying a little texture spray or hairspray helps the clips grip better.
Step 2: Section your hair
Start at the nape of your neck. Create a horizontal parting and clip the rest of your hair up.
Step 3: Apply the first weft
Snap open the clips, position the weft against your scalp, and secure from the centre outward.
Step 4: Work your way upward
Continue sectioning horizontally and applying larger wefts first, then smaller ones toward the crown and sides.
Step 5: Blend
Brush lightly to merge your natural hair with the extensions. Curling or waving your hair helps everything blend even more seamlessly.
Step 6: Style as desired
Because Hair Rehab London extensions are 100% human hair, you can curl, straighten, blow-dry and style them just like your own.
