Quick answer: Which developer volume to pick for Hicolor
Many stylists and color charts aim to simplify the decision, so here’s a direct answer that works for most clients. For most Hicolor applications use a 20-volume developer as your default; use 10-volume for pure deposit or very fine hair, 30-volume only when you need extra lift, and reserve 40-volume for stubborn dark bases and professional salon use with caution.

Choosing developer volume: what each number actually does
Understanding how developer strength affects lift and deposit is the first step. Developers are usually labeled 10, 20, 30, or 40 volume and each one delivers a different amount of lift or oxidation. This matters because Hicolor formulas respond to peroxide the same way other oxidative colors do: more volume equals more lift and greater chance of lightening the natural pigment.
For example, 10-volume gives minimal lift and mainly helps the color penetrate and deposit. Meanwhile, 20-volume gives up to two levels of lift for many clients, which is why it's the go-to. 30- and 40-volume deliver more lift but increase the risk of damage or unwanted brassy tones if you don't tone carefully.
Here’s a quick comparison you can keep handy:
| Developer | Effect |
|---|---|
| 10-volume | Deposit only, low lift |
| 20-volume | Standard lift (about 1–2 levels), balanced for most work |
| 30-volume | Stronger lift (about 2–3 levels), use with caution |
| 40-volume | Maximum lift, higher damage risk, professional use |
Overall, choose the lowest effective volume to protect hair health while achieving your target shade.

How hair porosity and condition change your choice
Porosity plays a big role in how developer behaves on the hair. High-porosity hair absorbs color faster and may over-process with higher developers, while low-porosity hair resists penetration and may need more time or a slightly stronger developer.
Next, take into account recent chemical services. For example, hair that’s been bleached or relaxed requires lower developers and gentler handling to avoid breakage. When in doubt, test a small section before full application.
Use this checklist to assess the hair before mixing:
- Check porosity with a strand test (squeeze wet hair or see how quickly water absorbs)
- Ask about recent chemical services (bleach, perms, keratin)
- Observe elasticity by stretching a small wet strand
Then adjust your developer choice accordingly: lower volume for fragile/highly porous hair; standard 20-volume for healthy, average-porosity hair; higher volume only for resistant, low-porosity hair with clear need for lift.

Matching desired lift and tone control with Hicolor
Decide first how many levels of lift you need and what tone you want. Lifting to a pale blonde needs more developer strength and careful toning afterward, while darkening or depositing color needs less strength and often a 10- or 20-volume developer.
If you want to lift and tone in one service, plan the sequence and the developer strength so you don’t overshoot the target. Many stylists lift with a stronger developer, rinse, then apply a toner mixed with a lower-volume developer to refine the shade.
Consider this ordered plan when targeting lift and tone:
- Assess natural level and target level
- Choose developer for controlled lift (start lower if unsure)
- Rinse and tone with a softer developer if needed
Remember that toners are delicate; using a 10–20-volume developer with toners usually gives the best, longer-lasting neutralization without excess lightening.
Mixing ratios, timing, and practical application tips
Mixing ratios affect processing. Many Hicolor products follow a 1:1 or 1:2 ratio with developer, but always read the product instructions. Correct ratios control the chemical balance and determine how quickly the color processes.
Timing matters too: higher developers work faster, so reduce processing time accordingly. For instance, a 30-volume mix will reach its peak lift faster than a 20-volume mix. Always check the hair periodically, for example every 5–10 minutes on a lift service.
Here are practical mixing notes you can use:
- Follow the Hicolor instructions first — they override general rules
- Start with recommended ratio, then adjust in small steps for color intensity
- Record time and results for future reference
Finally, perform a strand test before a full head application. It’s the best inexpensive step to predict outcome and avoid surprises.
Safety, scalp sensitivity, and minimizing damage
Safety must come first. Developer is an oxidizer and can irritate the scalp or damage hair when misused. Use gloves, protect the skin around the hairline, and never mix more than you will use in a single session.
When a client reports scalp sensitivity, choose the gentlest approach: lower-volume developers and patch tests. If a reaction occurs, stop immediately and rinse. Keep first-aid steps and contact information for medical help on hand.
Compare safety tips quickly in this table:
| Risk | How to reduce |
|---|---|
| Scalp irritation | Patch test, lower-volume developer, protect forehead |
| Hair breakage | Use lowest effective volume, deep condition, avoid overlapping bleach |
| Uneven lift | Section carefully, use consistent application, monitor timing |
Also, schedule deep conditioning and protein treatments after lifting services. Studies show that proper aftercare increases hair strength and client satisfaction.
Aftercare, toning, and keeping your results vibrant
After you process Hicolor with the right developer, aftercare preserves color and health. Use color-safe, sulfate-free shampoos and conditioner routines to extend tone and reduce fade. Many stylists recommend a purple shampoo for blondes to control brassiness.
Additionally, client education on heat protection, UV protection, and washing frequency helps results last. For example, washing hair less frequently and rinsing with cool water can keep color vibrant longer.
Follow this short routine to maintain salon results:
- Use sulfate-free shampoo and conditioner
- Apply a weekly deep conditioner or mask
- Use color-depositing products if needed to refresh tone
Finally, book a maintenance appointment every 6–8 weeks for professional toning or touch-ups depending on hair growth and color change. This keeps the color looking fresh and prevents long-term damage from repeated high-lift attempts at home.
In summary, choosing How Much Developer to Use With Hicolor comes down to a few clear rules: start with 20-volume for most jobs, lower the strength for fragile or deposit-only work, and only increase when you need real lift and you understand the risks. Use strand tests, protect the scalp, and follow product guidelines closely.
If you found this helpful, try a controlled strand test with the developer you’re considering and adjust based on the result. For more tips or a step-by-step salon checklist, leave a comment or book a consultation with a professional stylist to get personalized advice.
