Full Head Foils & Semi

What to Expect

Your appointment typically takes 2–3 hours and involves several carefully planned stages:

• Consultation and sectioning: Your colourist divides your hair into quadrants or patterns to ensure even, symmetrical placement
• Foil application: Fine slices or weaves are isolated in foils (often 50–100+ depending on density), then lightener or colour is applied to selected strands
• Processing: Foils process for around 30–45 minutes while your colourist monitors lift and tone
• Rinsing and semi application: After removing foils, a semi-permanent colour or gloss is applied across all or most of your hair to refine warmth, neutralise brassiness, and add uniform tone
• Finishing: Your hair is styled to reveal bright, dimensional colour with a glossy, blended finish

Weaving creates softer, more natural highlights; slicing produces bolder, more defined streaks. Your stylist will adapt the technique to suit your desired look.

Who This Service Suits

Full Head Foils & Semi is ideal if you want:

• Maximum brightness and contrast: Lightened pieces throughout your entire head for an all-over lifted effect
• Multidimensional colour: Depth, movement, and interest from root to tip
• Refined tone: The semi colour softens lines between highlights and base, combats brassiness, and adds a polished, uniform shade—warm, neutral, or cool
• A comprehensive change: More dramatic than partial or half-head foils, suitable for clients ready for significant brightening

This service works beautifully on most hair types, though very dark or previously coloured hair may require multiple sessions to achieve very light or cool-blonde results safely. Your stylist in Crawley will assess your starting colour and condition during consultation.

Aftercare and Maintenance

Preserving your colour and keeping lightened hair healthy requires thoughtful care:

• Wait 24–48 hours before your first wash to allow the semi colour to settle
• Use sulphate-free, colour-safe shampoo and conditioner to prevent fading
• Apply deep conditioning treatments weekly to maintain moisture and strength
• Limit heat styling and always use a heat protectant; avoid very hot water
• Consider toning or purple shampoos (when appropriate) to combat brassiness between visits

Full head foils grow out with visible regrowth at the roots. Most clients return every 6–10 weeks for foil maintenance, depending on hair growth and tolerance for roots. Semi-permanent glosses can be refreshed more frequently to maintain tone and shine.

Realistic Expectations

Your stylist will work with your hair's condition and history to achieve the best results safely:

• Pre-existing damage or very dry hair may limit how light you can go in one session; a gradual approach preserves hair health
• Very dark or heavily coloured hair lifts more slowly and may need multiple visits for dramatic lightening
• Time and cost: This is a comprehensive, time-intensive service using significant product and expertise
• Bring reference photos to help your colourist tailor foil placement, density, and semi colour tone to match your vision

For clients who prefer lower maintenance, your stylist can adapt placement and semi tone to create a more lived-in, rooted look that grows out softly with less visible regrowth lines.
