What to know before buying

Patch test 48 hours before each use and follow the pack safety instructions. Do not use on people under 16, on eyebrows or eyelashes, or where the listed allergy or scalp conditions apply. The warning also advises waiting at least two weeks after relaxing, perming or straightening, and not using on hair coloured with henna or progressive dye.

Listing details to confirm

Shade information conflicts: the title and contents description say 600 Dark Blonde, while product details and item type say 600 Light Brown. The listing also gives different duration claims, up to 32 shampoos and up to 28 washes, and the stated processing time appears in an unusual format. Confirm the shade and follow the instructions on the selected pack.

Who is it for?

A good fit for

People looking for ammonia-free semi-permanent colour with a glossy finish.
Those seeking to blend first greys rather than rely on guaranteed full grey coverage.
Buyers who prefer a cream format for at-home hair colouring.

Less suited to

Anyone needing a reliably confirmed dark-blonde result, since the listing also identifies this shade as light brown.
Anyone requiring dependable full grey coverage or a fixed duration, as customer reports and listing claims vary.
Anyone unable to complete the required allergy test or follow the product safety restrictions.

Customer feedback highlights easy application and a shiny finish, while shade results, grey coverage, longevity, value and hair condition are mixed. Some report the colour appears darker than expected, grey coverage is inconsistent, colour starts washing out after about three weeks, or hair condition suffers. These reports matter if you need an exact shade or dependable coverage and wear time. The listing's claims of up to 32 shampoos and grey blending should not be taken as assured results.

Positive themes

Customers describe application as easy.
Customers appreciate the shiny, glossy finish.

Mixed feedback

Reports differ on whether the colour matches expectations, including accounts that it looks darker than advertised.
Grey coverage and how long the colour lasts receive mixed feedback.
Value and effects on hair condition are also reported inconsistently.

Frequently asked questions

Is shade 600 dark blonde or light brown?

The listing is inconsistent. Its title and contents description call it 600 Dark Blonde, while product details call it 600 Light Brown. Check the selected product packaging before purchase.

How long is the colour claimed to last?

The listing gives two claims: up to 32 shampoos and up to 28 washes. Neither should be treated as a guaranteed duration.

Does it cover grey hair?

The manufacturer presents it for grey blending, particularly first greys, but customer feedback is mixed, with reports of both good coverage and little coverage.

What should I do before applying it?

Follow the instructions supplied with the product and perform the required skin allergy test 48 hours before each use. Observe the pack's full safety warnings.
