Evesel Bottle High Oxidizer

Capacity refers to the volume of developer liquid in the bottle - a high-capacity bottle holds more liquid for covering longer or thicker hair without running short. Strength (expressed in 'vol') refers to the hydrogen peroxide concentration - how much lifting and oxidation power the developer has. The shades in this collection include a high-capacity developer bottle that is also at a higher concentration than the standard 20 vol, because high-lift and toning applications consume more oxidiser chemistry than standard deposit shades.

You need a high-lift developer when the target shade requires three or more levels of lift from your natural starting colour. The standard 20 vol developer in regular EVESEL Gold shades lifts one to two levels - enough for most colour changes. The 12G Highlighter, 9N Ultra Light Tan, and 10G Bright and Strong Golden Blonde all need a higher-volume developer to complete their lift chemistry fully. These shades include the appropriate high-strength developer in the kit.

Control Line toners (TS Silver, AG Grey, GP Wine, BP Blue-Purple) are typically applied root to ends for uniform toning across the whole head, rather than being applied to roots only. A full-head toning application uses significantly more mixed product than a root retouch. The large developer bottle provides enough developer for the full application on medium-to-long hair without running short mid-session.

Yes, with a two-step approach. First, apply 12G Highlighter to lift natural hair to a pale yellow base (level 9-10). Rinse and wait 48 hours. Then apply Control Line TS Silver to tone the pale base to a bright silver-white. Both products are in this high-developer collection. The process works best on hair that has never been chemically treated; on previously coloured or damaged hair, the lift step may not achieve the required pale base in a single application and may need repeating. A strand test is essential before committing to the full process.

No - the 12G Highlighter still requires a full development time of 40-50 minutes to achieve maximum lift. High-lift formulas use stronger peroxide but the lift chemistry works gradually through the hair shaft over time, not instantly. Rinsing before 35-40 minutes will leave the result darker and less even than intended. The high-strength developer does mean the formula is more active immediately on application, which is why it is important to apply quickly and evenly before differential development creates variation from roots to ends.

On naturally dark hair (level 3-6), GP Wine deposits a deep burgundy that reads as a subtle dark maroon in low light and a richer wine-red in direct sunlight. The vivid burgundy result is more visible on medium-dark brown hair than on very dark (level 1-2) hair, where the result is a very deep maroon that is nearly indistinguishable from black in dim light. On grey and white hair, GP Wine appears as a vivid, deeply saturated wine-red because there is no competing natural melanin to dilute the dye deposit.

6V Bright Violet Blonde is an oxidative permanent colour that lifts the hair to a bright blonde depth while depositing a cool violet undertone. The result reads as a violet-tinted blonde - subtle and wearable for everyday use. BP Blue-Purple is a direct-deposit fashion toner that creates a vivid, saturated blue-purple result on already lightened hair. 6V is a complete colour change for medium-dark hair; BP Blue-Purple is a fashion toning step for hair already at a pale blonde level. The two shades produce very different results and should not be confused.

Yes. Higher-concentration hydrogen peroxide causes more cuticle disruption and melanin loss during development than standard 20 vol. This is why the high-lift shades (12G, 9N, 10G) should not be used more frequently than needed, and why the post-colour conditioner is particularly important after high-lift applications. The additional lift comes at the cost of some additional porosity and potential dryness. Deep conditioning in the week following a high-lift application helps restore moisture and elasticity.

Yes, if the existing colour is at a pale enough base. BP Blue-Purple deposits its vivid blue-purple pigment over whatever colour is already on the hair - it does not lift the existing colour. If the existing colour is a dark blonde or medium brown, BP Blue-Purple will produce a darker, muted version of the blue-purple rather than the vivid result seen on a pale base. For the most vivid BP Blue-Purple result, ensure the hair underneath is at level 9-10 pale yellow before applying, regardless of what put it there (natural growth-out, bleach, or 12G Highlighter).

AG Grey is formulated to neutralise warm (brassy, yellow, golden) tones on hair that has been lightened - it deposits cool ash pigment that counteracts orange and yellow. It works most effectively on hair that is at a level 7 or lighter. On darker hair (levels 4-6) with warm tones from a gold shade or natural warmth, AG Grey will add cool ash but the result may read as a darker ash-brown rather than a clear cool tone. For brassy tones on very light hair (level 8-9+), AG Grey is highly effective and can be left on for 20-30 minutes for a noticeable cool shift.
