Your hair still has that summer colour after being exposed to sun, ocean, and pool. But it’s already fall, and those slightly damaged reddish blonde tips that went so well with your summer look now make you look a little unkempt.

It is time to freshen up your hair colour, so why not make a big change to better set the tone for the season? Nothing goes with your fall-winter wardrobe anymore. It’s time for a transformation.

But beware, this is not to be taken lightly. The results may be catastrophic if you do not follow a few simple guidelines. We will not be talking about “at-home dye jobs” here, but about professional services like any good colourist should be able to provide.

Before anything can be done, corrections are often in order.

Although the term “colour correction” is often used in the context of damage control, when it comes to changing hair colour, usually “colour correction” needs to be done beforehand. Colour correction means prepping the hair so that it will be ready to receive the right colour, without false highlights or premature fading.

Put simply, if you want to lighten a dark dye job, you will have to remove the artificial pigment previously deposited on the hair. This process is delicate and can take many steps, but will not damage the texture if it is done properly.

If, on the other hand, you want to go darker, you’ll have to apply a “pre-pigmentation” to reconstruct the hair’s pigment base, depending on your desired result. If you skip this step, you will find yourself with a dull or even greenish colour, which will fade after the first few washes.

This fall, before jumping into anything, ask a professional colourist about the procedure to get the colour you want and ask for a quote. If you are still hesitant, or if the answers aren’t to your liking, it is always best to get a second opinion.

This weekend I’ll be in Paris for the “HFC” collections. I promise I’ll update you on the new trends next week.
