Going blonde from dark hair. Here is what nobody tells you.

Going blonde from dark hair is rarely a one appointment job. If you are anything darker than light brown, you are looking at two or three sessions to do it properly, and the price reflects that work.

I get asked about this every week, usually after a client has seen a Pinterest photo and thought it was one trip to the salon. It is not. The good news is the result is gorgeous when it is done right. The bad news is that anyone who promises it in one visit is either going to wreck your hair or quote you a colour correction price afterwards.

The short version

Box dye black to blonde takes at least 3 sessions, often more.

Natural medium brown to blonde takes 2 sessions, sometimes 3 for very pale ends.

One lifting session can only safely take hair up 2 to 3 levels.

A toner between visits keeps the blonde from going brassy.

Allow four to six weeks between sessions so the hair recovers.

Why one session is almost never enough

Hair has natural pigment running through it. To get from a dark brown or black to a clean blonde, we are lifting that pigment out and depositing a new tone over the top. Each lifting session can only safely take you up a few levels, because pushing further in one go is how you end up with broken, mushy hair.

If you have box dye sitting on top of your natural colour, that adds another layer. Box dye is harder to lift and tends to grab unevenly, which is why we sometimes need an extra session just to even out what is left after the first lift.

I would rather take three appointments and give you back hair that still feels like hair, than do it in one and hand you back something that snaps when you brush it.

Hair condition sets the timeline, not the price

When you come in for a consultation, the first thing I check is the porosity and strength of your hair. Two clients can both have dark brown hair and getting to blonde will look completely different depending on what their hair has been through.

If you have been heat styling daily for years, or you have stretched box dye colours, or your ends are already split, we go slower. Sometimes we will do a treatment session before we even start lifting, to get the hair ready. That extra step is not us upselling, it is the difference between a result you love and a result you cry about.

What going blonde from dark hair actually looks like

Session one is usually a half head of foils or a half balayage to break up the depth and bring some light through. We follow that with a toner so you leave looking finished, not stripey. Half balayage is £55 to £65, half foils are £55 to £65 too. A toner is £35 to £40, or £20 as an add-on.

Session two, four to six weeks later, fills in the gaps. Either a full balayage at £70 to £85, or full foils at the same price, depending on what suits your hair. Another toner, more depth taken out.

By session three, if you need it, we are pulling the colour right through to where you want it. By that point you are not going dark to blonde any more, you are doing the kind of refresh that keeps blonde clients in the chair every twelve weeks.

The bit nobody likes hearing about cost

Two to three sessions of professional colour at the prices above puts you somewhere between £150 and £270 to get to your blonde, plus a refresh appointment every twelve weeks or so. Klarna is available in the salon if you want to spread the first appointment.

If somebody quotes you £100 to do the whole thing in one go, ask them what brand of bleach they are using and how they plan to protect the hair. The honest answer is they cannot do it safely. Cheaper now usually costs more later, either in colour correction or in extensions to cover the damage.

Aftercare that makes the difference

Once you are blonde, the hair needs more help than it did before. A purple shampoo once a week, a proper bond repair treatment every wash for the first month, and please put the hot tools down on the highest setting. Blonde hair burns faster.

If you notice the scalp itching or going red after a colour appointment, that can be an allergic reaction to the dye itself, which is a form of contact dermatitis. New clients always get a patch test 48 hours before their first colour so we can rule it out before there is a problem.
