At-Home Hair Colour: How to Avoid 3 Common Buying Mistakes

Colouring your hair at home is a practical and cost-effective alternative to a salon visit. However, the selection of products at the drugstore can be overwhelming, and not every at-home hair colour delivers on its promise. Unwanted colour results, inadequate grey coverage, or damaged hair are common consequences of a hasty choice. As your Joybuy Product Recommendation Officer, I'll help you identify the typical pitfalls and make an informed decision.

The 3 Most Common Pitfalls When Buying Hair Colour

Many products advertise intense colours and perfect care. In practice, however, three common problems often lead to disappointment and unnecessary expense.

1. Inadequate Grey Coverage Despite Advertising Claims: Many colourants promise "100% grey coverage" but fail in practice on particularly resistant or a high percentage of grey hair. The result is often an uneven, patchy colour that requires another application.
2. Misleading Colour Representation on the Packaging: The hair colour shown on the box is an idealised image achieved under lab conditions. Your own starting hair colour, hair texture, and any pre-existing damage significantly influence the final result. Those who rely solely on the photo often face an unwelcome surprise.
3. Neglecting Post-Colour Care: Colouring is always a chemical process that stresses the hair. Many users focus only on the colour and underestimate the importance of the included conditioning treatment. A low-quality or undersized conditioner can leave hair feeling dry, brittle, and dull after colouring.

What to Look For Before You Buy: The Decisive Factors

To avoid these mistakes, you should check three core aspects before making a purchase. These will help you find an at-home hair colour that meets your requirements for colour, coverage, and care.

1. Type of Colour: Permanent or Wash-Out?

For a long-lasting colour change and reliable grey coverage, a permanent hair colour (Level 3) is the right choice. Unlike a semi-permanent dye, which washes out after a few shampoos, a permanent colour grows out with the hair. This is particularly relevant if you plan to regularly colour your roots. The pigments penetrate deep into the hair structure, ensuring an intense, durable result.

2. Coverage and Ingredients for Colour Depth

Look for explicit claims like "hair colour with 100% grey coverage". Brands such as Schwarzkopf hair colour or Poly Palette often have special product lines known for their high coverage. The formulation of the colour cream is crucial. Highly concentrated colour pigments that penetrate deep into the hair fibre are an indicator of an intense and long-lasting colour result.

3. Quality of the Care Formula

A high-quality, nourishing hair colour is essential to minimise hair damage. Check the ingredients of the included conditioning treatment. Formulations with nourishing oils (e.g., macadamia, argan, or apricot kernel oil) or special care systems (like Schwarzkopf's HaptIQ System) help to seal the hair structure after colouring, add moisture, and ensure shine. Brands like Garnier Nutrisse place a special focus on rich care components.

Frequently Asked Questions (FAQ)

1. How often can you colour your roots without damaging your hair?

It is generally recommended to touch up the roots every four to six weeks, as hair grows about one centimetre per month. To protect the lengths of your hair, you should only apply the colour to the new growth and work it through the lengths for just the last few minutes of the processing time to refresh the colour.

2. Is one box of hair colour enough for long or thick hair?

For shoulder-length or very thick hair, a single box is often not enough to achieve an even result. For a first-time application or if your hair extends well past your shoulders, it is advisable to buy two boxes. This ensures you have enough product to saturate the hair completely.

3. What is the difference between a drugstore hair colour and a professional one?

At-home hair colours are designed to be safe and easy to use for a wide range of hair types. They typically contain a standardised developer concentration. Professional colours used in a salon allow the colorist to customise the colour and the strength of the developer to the individual's hair texture, condition, and desired result. However, products in the best drugstore hair colour category today often feature advanced formulas that can achieve excellent results.
