Hair Mask Black Friday: More Room for Your Routine

Your weekly treatment, with one more reason to stock up

If you already know which mask works for your hair, a promotion can be the chance to switch to the large size. Before choosing, compare the price per litre or per 100 ml: the price of the tub alone doesn’t tell the whole story. Think about how much product you use and how often you wash, too. The more generous size makes sense when it supports a consistent routine, not when it risks staying open too long.

Fancy trying a brand you don’t usually buy? Start from a specific need rather than the discount alone. A formula suited to your lengths is a more useful buy than a jumbo size chosen only for its price.

Choose your mask based on what your hair is asking for

Nourishment: for dry, rough lengths

If your ends feel rough and your hair is hard to detangle, go for a nourishing mask. Plant oils and butters, together with conditioning ingredients, can help improve softness and combability. On thick or very dry hair you can consider rich textures; on fine hair, lighter formulas and smaller amounts work better. More product doesn’t necessarily mean a better result: what counts is finding the right balance without weighing hair down.

Colour: care for your lengths and tones to maintain

For coloured hair, look for a treatment designed for the needs of your lengths after colouring, with softness and colour-protection benefits stated on the product page. A mask for coloured hair isn’t necessarily pigmented: toning formulas, on the other hand, work specifically on tones and require their own leave-in times and frequency. If you want to work on blonde tones, explore our blonde hair Black Friday selection too and check what each treatment does.

Curls: softness without losing lightness

For curls, a mask should help detangle and soften the lengths without leaving a heavy feeling. Choose the texture based on hair thickness: fine curls may prefer a light texture, while thick, dry curls can benefit from a richer formula. Apply section by section and judge the result after rinsing and drying, before increasing the amount.

Large size or a new brand to try?

• Tried-and-tested formula: compare the quantities available and the cost per unit, checking that the range and version are the ones you usually use.
• First purchase: a smaller size lets you judge the texture, scent and results on your lengths before stocking up.
• New need: if you’ve changed colour, cut or styling habits, reassess your treatment instead of automatically rebuying the same one.

Have a professional brand in mind to add to your routine? In our Kérastase Black Friday selection you can compare the brand’s offers, choosing the right range first and then the size.

How to get the most from the mask you buy

After shampooing, squeeze out excess water, apply to the lengths and ends and distribute evenly. Avoid the scalp unless the product says otherwise. Respect the leave-in time shown on the pack and rinse thoroughly: leaving it on longer doesn’t automatically make the treatment more effective.

Frequency depends on the formula and your hair’s condition: a weekly ritual is a guideline, not a universal rule. For the washes when you don’t use a mask, you can consider our Black Friday conditioners, without adding steps you don’t need. Before buying your hair masks on offer, finally check the directions, quantities and period after opening: the best supply is the one you can use well.
