A half head semi applies semi-permanent colour to the top, crown and sides—the sections you see most—refreshing tone, boosting shine and softly blending regrowth. The colour gradually fades over several washes rather than growing out with a harsh line, making it a lower-commitment, maintenance-friendly alternative to full permanent colour.
More information
What to Expect
Your stylist will section the hair to focus on the most visible areas, applying semi-permanent colour evenly through the top layers. The colour coats the hair shaft rather than penetrating deeply, so it enhances tone and shine without permanently altering the structure. After processing and rinsing, you'll see richer, more vibrant colour through the crown and sides, with natural depth remaining underneath for a soft, sun-kissed effect.
Who It Suits
This service is ideal if you want to:
- Refresh faded colour or add vibrancy without full-head commitment
- Blend regrowth softly in the most visible sections
- Add depth, tone or shine to natural or previously coloured hair
- Trial a new shade before committing to permanent colour
- Keep maintenance simple with colour that fades naturally over 4–12 washes
Because semi-permanent colour sits on the surface, it's not suited for full grey coverage or dramatic lightening—permanent or demi-permanent options work better for those goals.
Aftercare & Longevity
Semi-permanent colour typically lasts 4–12 washes depending on hair porosity, wash frequency and home care. To maximise vibrancy:
- Use colour-care shampoo and conditioner to protect tone
- Limit heat styling and always use heat protection
- Avoid harsh clarifying shampoos, chlorinated pools and prolonged sun exposure
Most clients return every 4–8 weeks for a refresh, though those washing daily or wanting very consistent tone may choose more frequent visits.
Maintenance & Alternatives
A half head semi offers a time- and cost-efficient middle ground: more noticeable than a toner alone, less commitment than full permanent colour. If you want all-over even colour, consider a full head service; for added dimension and brightness, explore half head highlights or balayage. Your stylist in Crawley will recommend the best approach based on your hair history, condition and goals during your consultation.
