3 Reasons Why I Love Foiling (and How to Look After It at Home)

Foiling is one of those hair services that never goes out of style — and for good reason. When done well and looked after properly at home, foils can look fresh for weeks… even months. I’m often asked how long foiling lasts, and the answer is simple: it depends on placement and aftercare.

Foiling can last anywhere from 6 weeks to 3 months, and when you pair a great colour service with the right home haircare, the results speak for themselves.

Here’s why I truly love foiling — and how you can make it last longer at home.

1. Foiling Creates Dimension That Grows Out Beautifully

One of my favourite things about foiling is the soft, natural dimension it creates. Foils allow colour to be placed exactly where it’s needed — around the face, through the crown, or blended seamlessly throughout the hair.

Because foils are strategically placed, they grow out far more naturally than block colour. That means fewer harsh regrowth lines and a softer transition as your hair grows, which is why many clients can comfortably stretch their appointments out to 10–12 weeks.

✨ It’s colour that works with your hair, not against it.

2. Foiling Is Completely Custom to You

No two heads of hair are the same — and foiling allows for complete customisation. Whether you want bright, bold blondes, soft lived-in tones, or subtle lightness, foiling can be tailored to your hair type, lifestyle, and maintenance level.

This is where longevity really comes into play. Thoughtful placement means your foils can be designed to:

• Frame your face

• Add lightness without overdoing it

• Blend beautifully with your natural colour

When foils are placed with intention, they don’t just look good on day one — they continue to look good for months.

3. Foiling Gives Long-Lasting Results (With the Right Care)

Foiling is an investment, and when you care for it properly, it truly pays off. With professional-grade haircare at home, your colour stays brighter, healthier, and more vibrant for longer.

This is where the 6 weeks vs 3 months difference really matters.

Using supermarket shampoos or over-washing can strip toner and fade colour quickly. On the other hand, nourishing, colour-safe products protect your foils and extend their life — meaning fewer salon visits and consistently beautiful hair.

How to Look After Your Foils at Home

Want your foils to last as long as possible? Here’s how to protect them between appointments:

Use professional, colour-safe products
A sulphate-free shampoo and conditioner designed for coloured hair is essential. These protect the toner and keep your colour from fading too fast.

Wash less, protect more
Try to limit washing to 2–3 times per week. When heat styling, always use a heat protectant to prevent colour dullness and dryness.

Hydration is everything
Foiled hair loves moisture. A weekly treatment or mask will keep your hair strong, shiny, and healthy — which helps colour stay vibrant.

Purple or toning products (when recommended)
Used correctly, these help maintain blonde tones without over-drying your hair. Less is more here — your stylist will guide you.

My Thoughts

Foiling is one of the most versatile and long-lasting colouring techniques when done thoughtfully and supported with the right home care. Whether your foils last 6 weeks or up to 3 months, the difference is in placement, product choice, and how you care for your hair at home.

Beautiful colour doesn’t stop at the salon — it continues with what you do every day.
