Diane Perfect Extra Night Repair: A Quick Guide

Diane's Perfect Extra Night Repair line is a small, focused hair care system for hair that feels dry, brittle or chemically stressed. This guide walks through what each product does and how to build them into a routine that actually shows results.

What the Perfect range is for

The Perfect Extra Night Repair line targets damage from colouring, heat styling and daily wear. The idea behind the name is overnight repair: the treatment and mask are formulated to keep conditioning your hair after you have rinsed and dried it, so the benefit carries through to the next day. It is a good fit if your ends split easily or your hair feels rough after washing.

Perfect Extra Night Repair Shampoo

The 450ml shampoo is the first step. It cleans without stripping, which matters for damaged hair that loses moisture fast. Work it through wet hair, focus on the scalp, and let the lather run down the lengths rather than scrubbing the ends. Rinse well before moving on to the treatment.

Perfect Extra Night Repair Treatment

The treatment is your daily conditioner, also in a 450ml bottle. After shampooing, smooth it from mid-length to ends, leave it for a minute or two, then rinse. There is also a Perfect Beauty Extra Night Repair Treatment version in the range if you want to compare formulas. For convenience, the shampoo and treatment also come as a paired set.

The intensive hair mask

The 180g Perfect Extra Night Repair Hair Mask is the deep-treatment step. Use it once or twice a week in place of your treatment when hair feels especially dry. Apply to clean, damp hair, leave it on for three to five minutes, and rinse. There is also an Extra Damage Repair Hair Mask in the collection for very compromised hair.

Building a weekly routine

A simple plan: use the shampoo and treatment on every wash, then swap the treatment for the mask once or twice a week. If your hair is only mildly dry, the daily shampoo-and-treatment pairing may be enough on its own. Heavily processed hair benefits from leaning on the mask more often.

Who should reach for this line

This range suits coloured, bleached, permed or heat-styled hair that has lost its smoothness. If your hair is fine and gets weighed down easily, go lighter on the mask and concentrate the treatment on the ends. Thicker or coarser hair can use the full system more generously.

FAQ

Frequently asked questions

  • It centres on the Perfect Extra Night Repair line: the repair shampoo, the treatment (including a Perfect Beauty version), and the intensive hair mask, all in 450ml or 180g sizes. There is also a shampoo-and-treatment set and an Extra Damage Repair Hair Mask for more compromised hair.

  • The name points to overnight conditioning. The treatment and mask are made to keep working on your hair after rinsing and drying, so the smoothing and repair benefit carries through until your next wash. It is built for hair damaged by colour, heat or daily wear.

  • Shampoo first, focusing on the scalp, then rinse. Apply the treatment from mid-length to ends on every wash and rinse after a minute. Swap the treatment for the mask once or twice a week when your hair feels especially dry, leaving it on for three to five minutes before rinsing.

  • It is aimed at dry, coloured, bleached, permed or heat-styled hair that has lost smoothness. Fine hair should use the mask sparingly and keep the treatment on the ends, while thicker or coarser hair can use the full system more freely.

  • The paired shampoo-and-treatment set is the easy starting point if you want the core routine. Add the hair mask separately when you want a deeper weekly treatment, or pick a single product if you only need to fill one gap in your current routine.
