What Does Developer Do?
Developer is hydrogen peroxide in a cream base, and it’s the second a part of your hair coloration system. You combine it with the precise dye to activate it, and with out it, the colour molecules can’t penetrate your hair shaft.
They’d simply sit on the floor and wash proper off.
Right here’s the way it works: developer opens the hair cuticle, which is the outer protecting layer of every strand. This permits coloration molecules to get contained in the cortex the place they will do their job.
The upper the amount, the extra it opens the cuticle, and the extra raise you get.
The volumes of developer check with how a lot hydrogen peroxide the developer incorporates. Extra peroxide means extra raise. Much less peroxide means extra deposit.
Hair Ranges: What You Have to Know First
Earlier than we get into the precise volumes of developer, it helps to grasp hair coloration ranges as a result of that is what makes the whole lot else make sense.
Hair coloration is measured on a scale from 1 to 10. Degree 1 is black and degree 10 is the lightest blonde. The upper the quantity, the lighter the hair. For instance, medium brown is a degree 4.
While you’re coloring your hair, you have to know two issues: your present degree and your goal degree. You may normally discover your goal degree by trying on the quantity in your hair coloration field.
A coloration labeled 5N means the goal result’s a degree 5.
To make clear, this doesn’t clarify the colour’s hue; it’s only a method to measure how mild or darkish the colour is.
Raise vs. Deposit
That is the opposite factor you have to perceive earlier than selecting a developer.
Raise means making the hair lighter. In case your hair is a degree 5 brown and also you need to go to a degree 7 blonde, you have to raise two ranges.
Deposit means making the hair darker. In case your hair is a degree 7 and also you need to go to a degree 5, you’re depositing coloration.
The amount of developer you select relies upon totally on whether or not you’re lifting, depositing, or someplace in between.
Remember the fact that virgin hair coloration (hair that has by no means been coloured) reacts otherwise than coloured hair. Learn extra in regards to the golden rule of lifting hair coloration.
What Are The Completely different Volumes of Developer?
10 Quantity Developer (10V / 3% peroxide)
10 quantity is the gentlest developer and the one you utilize if you solely need to deposit coloration with none raise. It barely opens the cuticle, simply sufficient to let coloration molecules in with out inflicting any lightening.
Use 10 quantity if you’re going darker than your present coloration, making use of a toner or glaze, utilizing a demi-permanent coloration, or including a tint with out altering your degree.
10 quantity is not going to lighten your hair, so don’t count on raise if you use it.

⚠️ Received’t work for: Grey protection, lifting, or lightening
💬 Merchandise price making an attempt: Clairol Pure White 10 Quantity Developer

20 quantity is probably the most generally used developer in skilled salons, and for good cause. It lifts the hair 1-2 ranges and offers sufficient processing energy for dependable grey protection, making it the candy spot for most traditional coloration purposes.
After I was within the salon, 20 quantity was my default developer for almost all of coloration companies. Most girls doing customary all-over coloration at residence ought to be reaching for 20 quantity robotically.
Use 20 quantity if you’re protecting grey hair, staying at your present degree or going 1-2 ranges lighter, doing an all-over coloration with a normal everlasting dye, or touching up roots.
✅ Greatest for: Grey protection, customary everlasting coloration, 1-2 ranges of raise
⚠️ Heads up: Not robust sufficient for important raise on darkish or resistant hair

30 Quantity Developer (30V / 9% peroxide)
30 quantity lifts the hair as much as 3 ranges and is the developer you attain for when 20 quantity doesn’t minimize it. It’s generally used with lightener and for extra important coloration adjustments on virgin hair.

30 quantity is extra highly effective than 20 and causes extra cuticle disruption, which implies extra potential for dryness and harm if the hair is already compromised. All the time assess the situation of your hair earlier than reaching for 30 quantity.

40 quantity is the strongest developer you need to ever use at residence. It lifts the hair as much as 4 ranges and is often used with lightener or high-lift blonde coloration on coarse, resistant virgin hair.
Right here’s my trustworthy recommendation about 40 quantity: watch out with it. When used with bleach, 40 quantity could cause severe harm if the hair is already compromised, over-processed, or high quality.
The raise is highly effective, however so is the harm potential.
Some high-lift colours even require a double 40 quantity utility for further raise, however that’s a really particular state of affairs and never one thing I’d suggest making an attempt at residence and not using a stable understanding of hair chemistry.
✅ Greatest for: Most raise, high-lift blonde coloration on virgin hair
⚠️ Heads up: Probably the most damaging developer. By no means use on compromised or beforehand bleached hair.
5 and 6 Quantity Developer
These lower-strength builders don’t come up as usually however they’re price realizing about. 5 and 6 quantity are usually used with glazes and toners the place you need to activate the colour with minimal impact on the cuticle. They’re additionally utilized in some demi-permanent coloration strains.
They gained’t raise your hair in any respect and gained’t present grey protection. Their solely job is to activate the colour molecules with light processing.
Which Developer Do I Use With Bleach?
This is likely one of the commonest questions I acquired at Sally Magnificence, so let’s deal with it immediately.
With bleach, the developer you select is determined by how a lot raise you want and the situation of your hair.
20 quantity with bleach provides you a slower, gentler raise and is finest for high quality or fragile hair, or if you’re doing a refined lightening service. It provides you extra management over the method.
30 quantity with bleach is the commonest selection for traditional bleaching companies as a result of it gives a superb steadiness of raise and management.
40 quantity with bleach provides you most raise but in addition carries the very best harm danger. Solely use this if in case you have coarse, resistant virgin hair that actually wants it, and by no means on broken or beforehand chemically handled hair.
A basic rule: when unsure, go decrease. You may at all times re-bleach should you want extra raise, however you can’t undo harm from utilizing too robust a developer.
Which Developer Do I Use for Grey Protection?
20 quantity developer is the usual advice for grey protection. It opens the cuticle sufficient for coloration to penetrate resistant grey hair and offers dependable, even protection.
In case your grey is especially resistant and also you’re not getting full protection with 20 quantity, you may strive 30 quantity, however at all times begin with 20 first.
One necessary notice: 10 quantity is sort of by no means sufficient for grey protection. The cuticle doesn’t open sufficiently for the colour to completely penetrate resistant grey strands, which is why protection usually seems to be patchy or fades rapidly when 10 quantity is used.
What Occurs If You Use the Unsuitable Developer?
That is the half no one talks about sufficient, so let’s cowl it immediately.
If you happen to use too low a quantity, the colour gained’t raise sufficient and also you’ll find yourself with a end result that’s darker or much less vibrant than you needed. With grey protection, you may get patchy, uneven outcomes that fade rapidly.
If you happen to use too excessive a quantity, the colour processes too quick and may raise greater than you supposed, leaving you with uneven coloration or sudden heat. With bleach, utilizing too excessive a quantity on compromised hair could cause breakage, and in excessive instances it might trigger severe harm.
Utilizing a 40 quantity developer with everlasting coloration if you solely wanted 20 gained’t offer you further raise. It is going to simply harm your hair extra. Greater shouldn’t be at all times higher.
