Hair Mask

A hair mask is conditioner with the good parts turned up and the water turned down. More oils, more butters, more of the clinging agents, plus a thick texture that stays where you put it for the 5 to 20 minutes the label asks for. Contact time is the actual product here. Rinsing one out after 60 seconds leaves you with an expensive conditioner and nothing else.

Masks split into two jobs, and mixing them up causes most complaints. Moisture versions bring softness and flexibility through oils and humectants, ingredients such as glycerin that pull water into the strand. Protein versions carry hydrolyzed keratin or wheat protein that patch gaps in a damaged surface and stiffen it. Hair that stretches like chewing gum when wet is asking for protein; hair that snaps dry and feels rough is asking for moisture. Overdo protein and hair turns brittle, a symptom people usually misread as needing still more protein.

Where a rinse out conditioner is a step in every wash, this is a weekly appointment. Hair oil differs by location rather than strength: a mask works while it soaks and then leaves, oil stays on the surface all day. The light daily version of the same idea is a leave in. Bond building treatments sold as repair use separate chemistry aimed at internal links broken by bleach, and they go on before or with shampoo, not in place of this.

Bleached, highlighted, heat styled, coily and very long hair all show real returns. Anyone swimming in chlorinated water more than twice a week should be masking weekly. Warmth speeds the process, so a shower cap or a warm towel for 10 minutes roughly doubles what the same tub achieves in a cold bathroom. Fine, straight, uncolored hair does not need one weekly and goes limp for two days if it gets one. So once a month on the ends is plenty.

Apply to damp hair rather than dripping hair, because water already in the shaft blocks the treatment from getting in. Work from the ends upward and stop about two inches short of the scalp. Rinse for a full minute, since incomplete rinsing is the usual reason a mask leaves hair greasy the next morning. Clean dry fingers or a scoop keep a tub usable, as water and bacteria in an open jar cut its life to a few months.
