Hair Prep Before an Event: Cuts, Colour and Wash-Day Timing

The hair you bring to your appointment has a big effect on how the finished style looks and lasts. Fresh colour, the right amount of cleanliness and a trim at the right moment all make your stylist's job easier. This guide covers the few weeks before an event, the day before and what to do on the morning.

Haircuts: timing is everything

A cut the day before sounds sensible but leaves no room to recover if it goes wrong, and very blunt fresh ends can be harder to style. Many people aim for a trim about one to two weeks before the event, which gives the cut time to soften and still looks fresh. If you are planning a big change in length or shape, do it much earlier, ideally before your trial, so the stylist can plan the look around your new hair.

If you want an updo, tell your hairdresser before they cut. Removing a lot of length or adding many short layers can make pinning trickier; they can adjust the cut to keep your options open.

Colour: book it early, then refresh

A new colour, or a big change like going much lighter, is best done well in advance. It gives time for any adjustments and lets you see how it settles. A root touch-up or gloss can then be done around a week before the event, a timing many colourists like because the colour looks fresh without being brand new. Always follow your colourist's recommendation; they know your hair and the products used.

When	What
2–3 months out	Any big colour or cut change; trial booked after this
1–3 months out	Hair and makeup trial
About 2 weeks out	Trim to tidy the ends
About 1 week out	Root touch-up or gloss if needed
Night before or morning	Wash as your stylist instructs

To wash or not to wash?

This is the question stylists hear most. The answer depends on your hair and the style, which is why you should ask your stylist directly. As a general pattern:

• Updos often hold better on hair washed the day before, because freshly washed hair can be slippery and pins slide out.
• Blow-outs and down styles often look best on hair washed the same day or the night before.
• Fine hair can get oily quickly, so some stylists prefer it washed the night before.
• Curly or coily hair may have its own routine; your stylist might want it freshly washed and defined, or stretched.

Skip heavy conditioning masks and oils right before your appointment unless your stylist asks for them, as they can weigh hair down and make it harder to hold a style.

How to arrive at your appointment

• Hair washed as instructed and completely dry, unless told otherwise
• No hair ties or clips that leave dents; wear it loose
• No heavy oils, serums or dry shampoo unless asked
• A button-up or zip-up top so you can change without disturbing hair
• Your accessories, veil or headpiece
• Photos of the style from your trial

Wearing a top that buttons or zips up the front is a small but important detail. Pulling a jumper over a finished updo is a classic mistake.

Tell your stylist about treatments and extensions

Some treatments change how hair behaves. Smoothing or keratin-type treatments can make hair very sleek, which is lovely for straight styles but can make curls drop. Perms or relaxers may affect how your hair responds to heat. Extensions, whether clip-in, tape or sewn, need to be planned into the style. Your stylist can only account for these if they know, so mention them when you book and again at the trial.

Caring for your hair in the weeks before

Healthy hair holds styles better. In the run-up to an event, go gently with heat, use a conditioner every wash, and consider a nourishing treatment occasionally if your hair tends to be dry. Protect it from sun and chlorine where you can. Avoid trying a brand-new product line or a dramatic at-home treatment in the final week; stick to what you know works.

Scalp and sensitivity

If you have a sensitive scalp, tell your stylist. Tight styles and many pins can be uncomfortable, and some products may irritate. A stylist can use fewer, well-placed pins and lighter styles to keep you comfortable all day. If you have a scalp condition, ask a qualified professional for advice on caring for it before the event.
