Will semi permanent rinse cover grays?

Going gray can be a natural part of aging, but some people prefer to cover up their grays rather than embrace them. Semi-permanent rinses offer a temporary way to mask grays between salon visits. Here’s what to know about using semi-permanent rinse to cover grays.

What are semi-permanent rinses?

Semi-permanent hair rinses are colored liquid formulas that coat the hair strand. They last through several shampoos before fading out. Semi-permanent rinses come in a variety of shades to enhance natural hair color or cover grays.

Semi-permanent rinses differ from permanent hair dye because they don’t penetrate the hair shaft or cause permanent color change. The rinses wash out over time, so roots will show as hair grows in. Frequent applications are needed to maintain full gray coverage.

Can semi-permanent rinse cover grays effectively?

Semi-permanent rinses can temporarily cover gray hairs, but results may not be as complete or natural-looking as permanent dye. Here are some pros and cons of using semi-permanent rinse on gray hair:


  • Quick, easy application at home between salon visits
  • Less commitment than permanent dye since color washes out gradually
  • No need to do touch-ups as roots grow in
  • Color options include subtle highlights/lowlights or temporary fantasy shades
  • Lower risk of damage to hair than permanent dye


  • May not cover coarse or resistant grays completely
  • Color tends to look more artificial, especially at roots
  • Frequent reapplication needed to maintain coverage as rinse fades
  • Color washes out unevenly leading to obvious regrowth
  • Less natural-looking results compared to permanent color

The success of gray coverage comes down to hair type and condition. Fine, porous grays tend to absorb semi-permanent color better than coarse, resistant grays. Rinses work best for blending or refreshing salon color rather than achieving complete gray coverage on their own.

Tips for using semi-permanent rinse on grays

If you want to try a semi-permanent rinse to mask grays, here are some tips for best results:

  • Prep hair: Use a clarifying shampoo first to remove product buildup. Rinses absorb better into clean hair.
  • Know your grays: Determine how much gray hair you have and how resistant it is to covering. This sets expectations for the rinse results.
  • Do a strand test: Try the rinse on a small section first to see if it covers grays adequately and preview the color.
  • Apply thoroughly: Divide hair into sections and use applicator bottle to disperse rinse from roots to ends.
  • Process fully: Leave rinse on for 5-15 minutes as directed on the packaging for optimal gray coverage.
  • Enhance the color: Under-base with a demi-permanent dye or gloss to boost gray coverage and shine.
  • Refresh often: Reapply rinse as soon as gray regrowth becomes obvious, usually every 2-4 weeks.

It also helps to choose a rinse formula specifically made for covering grays. Look for ingredients like proteins or oils that cling to resistant grays. Warm rinses under a hooded dryer can also improve gray coverage compared to just using at room temperature.

Which brands cover grays the best?

The most effective semi-permanent rinses for masking gray hair typically come from professional beauty brands. Some top options include:

Brand Product Details
Clairol Nice’n Easy Color Blend Service Demi-permanent liquid hair color with portulaca extract to target grays
Schwarzkopf Colorance Hair Toner Ammonia-free rinse with pearl essence for luminous color

Drugstore brands like L’Oreal, Revlon, Garnier, and John Frieda also offer at-home semi-permanent rinses to cover gray hair between salon visits.

How long does semi-permanent rinse last on gray hair?

Semi-permanent rinse typically lasts around 4-6 shampoos on gray hair. Exact longevity depends on:

  • Porosity of hair – More porous hair holds onto color longer
  • Coarseness of hair – Fine hair retains color better than coarse
  • Frequency of shampooing – Frequent washing fades color faster
  • Use of hot tools – Heat styling can accelerate fading
  • Exposure to sun – UV rays diminish hair color
  • Type of shampoo – Clarifying or anti-dandruff shampoos strip color more

Even when used on resistant gray hair, most semi-permanent rinses last about 2 weeks. Regrowth becomes visible as the dark tinted rinse fades from mid-lengths and ends first. Roots tend to show faster than the rest of the hair.

To keep grays consistently covered, plan for reapplication every 2-4 weeks. Some brands offer temporary color conditioners or toning mousses that can refresh color between rinse treatments.

Are there risks to using semi-permanent rinse on gray hair?

Semi-permanent hair rinses are less harsh than permanent dye since they simply coat the hair shaft rather than penetrate it. However, potential risks include:

  • Skin irritation – Rinses contain lower levels of chemicals than permanent color but can still cause skin reactions, especially near the scalp and hairline.
  • Hair damage – Any hair coloring treatment can weaken or dry out hair over time with consistent use.
  • Uneven results – If rinse isn’t applied thoroughly from roots to ends, a demarcation line can appear as it fades.
  • Color build-up – Overlapping rinse applications without properly removing previous color can leave hair discolored.
  • Unexpected color – Underlying pigment, whether natural or from dye, can mix with rinse to create undesired tones.

Doing a patch test before using a new semi-permanent rinse can identify any potential irritation or allergic reaction. It’s also smart to consult a colorist if you have color treated hair to ensure proper use of rinse products at home.


Semi-permanent hair rinses offer easy, temporary gray coverage in between salon visits. While they may not fully cover resistant grays like permanent dye, rinses provide an option for blending roots or experimenting with new colors.

Getting the best results requires proper application techniques, understanding your gray hair characteristics, and using quality rinse formulas designed for gray coverage. Even then, expect to reapply every few weeks as the color fades. Although lower maintenance than permanent dye, semi-permanent rinse requires repeated use to keep grays concealed.

Consult a professional hair colorist to determine if semi-permanent rinse can effectively cover your grays. With the right strategies and expectations, these temporary color solutions can help you refresh your look in between permanent salon appointments.
