At-Home vs Professional Colour

At-home or professional hair colouring: which approach suits you?

At Lavender Hair, colouring begins with your scalp, grey hair, previously coloured sections and ends. We then plan natural-looking colour and aftercare for each area.

What to considerCommon limitations of at-home colouringLavender Hair's professional approach
Before colouringChoosing only from the shade on the box can overlook your scalp's condition that day and any previous reactions.We ask about past reactions, check the scalp and distribution of grey hair, and arrange testing according to the product instructions.
Applying colourUsing one box across roots, previously coloured lengths and ends can repeatedly process sections with different levels of damage.We treat regrowth, grey hair, previously coloured sections and ends separately to minimise unnecessary overlap.
Scalp contactColouring your own hair makes it harder to see the back of your head, control the hairline and time each section.We use protective measures, manage contact areas and timing, and check how your scalp feels throughout.
Hair condition after colouringOxidative colouring opens the cuticle so colour can enter the hair. Inappropriate processing can leave hair dry, frizzy or prone to breakage.After colouring, we cleanse the scalp separately and provide moisture and conditioning protein according to the hair's condition.

“Colouring makes hair coarser every time” is not always accurate. Cumulative dryness and breakage are the real concerns.

Different types of hair colour work differently. Permanent oxidative colour needs pigment to enter the hair shaft, and repeatedly covering damaged areas can increase dryness, frizz and fragility. Lightening usually requires stronger peroxide and places more stress on the hair. This is why Lavender Hair focuses on natural-looking colour, grey coverage and manageable upkeep rather than fashion shades that require bleaching.

What Lavender Hair means by “colour exchange”
We work section by section according to regrowth, grey hair, previously coloured lengths and ends, combining colour with moisturising and hair care. This does not mean colouring causes no damage. The aim is to avoid unnecessary processing and leave a clear plan for your next visit.

Please tell us about metallic dyes, black dyes or products of unknown origin.

Products used in the past can affect later colour reactions and how we approach your service. Do not mix different hair dyes yourself. If you have used metallic-salt dyes, black dyes, henna or products of unknown origin, tell us when booking.

Frequently Asked Questions

Common Questions, Clear Answers

Start with the essentials, then explore what they mean for your circumstances.

Why should I look beyond the shade before colouring at home?

At-home products usually have fixed formulas and general instructions. They are harder to adapt section by section to grey distribution, previously coloured areas, damaged ends and your scalp's condition that day.

Does professional colouring guarantee no allergic reaction?

No. Any hair colour can cause an individual reaction. Professional care adds value through consultation, testing according to instructions, section-by-section application, contact management and a prompt response to discomfort.
