Chez Salon En Vogue, ammonia-free colour is central to our responsible approach to beauty at Montréal. From our Old Port salon, we see growing demand for gentler colour options. Today's women want beautiful colour without compromising the health of their hair.
Ammonia was long the key ingredient in permanent colour, opening the hair cuticle so pigments could penetrate. It works, but can be harsh on the hair fibre. Advances in cosmetic chemistry now offer effective alternatives that truly change the experience. Here is what to know before making the switch.
What exactly is ammonia-free colour?
La ammonia-free colour replaces ammonia with gentler alkaline agents, most commonly monoethanolamine , or MEA. These substitutes open the cuticle in a much gentler way.
The different formulas available
Not all ammonia-free colour is equal. There are three main categories:
- Permanent ammonia-free colour: it provides complete grey coverage and lasting wear while treating hair more gently. This is our preferred option at Salon En Vogue for clients seeking lasting colour.
- Demi-permanent, tone-on-tone colour: with no ammonia and little or no peroxide, it deposits colour without lightening. It is ideal for refreshing natural colour, adding dimension or blending the first greys.
- Plant-based colour: made with dye plants such as henna, indigo and cassia, these are the gentlest formulas but offer a more limited palette and may not fully cover grey hair.
The tangible benefits of ammonia-free colour
Why are more Montreal women choosing it? The benefits are numerous and tangible:
1. Better-preserved hair fibre
Ammonia can cause structural damage by breaking disulfide bonds in keratin. Without ammonia, hair retains more of its integrity, leaving it softer, shinier and less prone to breakage. For clients who colour every four to six weeks, the long-term difference is considerable.
2. Exceptional comfort during application
There is no sharp odour, stinging or itching. Ammonia-free colour is far more pleasant for both client and stylist, and especially welcome for sensitive or reactive scalps.
3. More natural, luminous dimension
Ammonia-free formulas deposit colour more evenly and translucently. Highlights look natural, with depth and dimension rather than the solid effect some traditional colour can create.
4. Softer grow-out
The line between coloured hair and natural growth is softer. Colour fades gradually, naturally spacing out touch-up appointments.
Ammonia-free versus traditional colour: an honest comparison
Ammonia-free colour also has limitations. Here is an objective comparison to help you make an informed choice:
- Grey coverage: traditional colour can provide 100% coverage in one application. Ammonia-free formulas generally cover 70% to 100%, depending on the formula and amount of grey. The professional ranges we use at Salon En Vogue achieve complete coverage.
- Lightening power: ammonia can lift hair three to four levels, while ammonia-free colour is generally limited to one or two. A dramatic change from dark to blonde still requires lightening or balayage .
- Colour longevity: professional-quality ammonia-free colour lasts as long as traditional colour, generally four to eight weeks depending on washing frequency.
- Price: professional ammonia-free formulas cost slightly more, reflecting ingredient quality and better long-term preservation of the hair.
Who is it ideal for?
Ammonia-free colour is especially recommended if:
- You colour your hair frequently , every four to six weeks, and want to limit cumulative chemical damage.
- You have a sensitive scalp, including eczema, psoriasis or general sensitivity to chemical products.
- You are pregnant or breastfeeding and prefer a gentler option. Always consult your physician.
- Your hair is already sensitized by previous chemical services such as relaxing, perming or repeated bleaching.
- You want a natural result, such as refreshing colour, enriching dimension or blending a few greys without a dramatic change.
- You are environmentally conscious and are looking for products with less environmental impact.
Why choose a professional salon for ammonia-free colour?
Mass-market ammonia-free products and professional formulas are worlds apart. Here is why salon results are incomparable:
- Hair assessment: our coloristes assess your hair's condition, colour history, scalp and goals before choosing a formula. A boxed product cannot provide this diagnosis.
- Customized formula: salon colour is mixed to measure. Tone, developer strength and processing time are tailored to your hair.
- Ingredient quality: professional ranges contain hair-care ingredients such as keratin, botanical oils and ceramides that condition hair during colouring.
- Expert application: even, strategic application ensures a seamless result without patches or overloaded areas.
