Damaged hair care: how to choose a routine that suits you without blowing your budget

Dry hair, snagging ends, breakage after colouring or a lack of shine despite piling on products: damaged hair treatments don’t all address the same issues. The first step is to pinpoint the problem, rather than falling for the promise of a supposedly one-size-fits-all product.

Common pitfalls before you buy

1. Confusing cosmetic effect with lasting repair

A treatment can make hair feel softer, shinier and easier to detangle from the very first use, thanks to conditioning agents, oils or silicones. This result improves the look and feel of the hair fibre, but it doesn’t mean split ends have been permanently mended. A split end that has already formed cannot be durably glued back together by a cosmetic product – only a trim can truly get rid of it.

2. Choosing a formula that’s too rich or too high in protein

On fine hair, a build-up of oils, butters or conditioning films can quickly lead to a loss of volume. Conversely, hair that’s been severely weakened by bleaching, heat or chemical treatments can benefit from a protein hair mask used occasionally. However, too much protein can leave hair feeling stiff, even dry. It’s best to alternate between hydration, nourishment and protein.

3. Relying solely on the word ‘repair’

The term ‘repairing’ doesn’t tell you much about the ingredients or how the product should actually be used. Check its category, the recommended leave-in time, the format and the ingredient list. A shampoo is primarily for cleansing the scalp, whereas a repairing conditioner mainly works on the lengths. For coloured hair, how often you wash and how gently you cleanse are just as important.

The criteria to check for a consistent routine

1. Match the product to the area that’s actually damaged

Shampoo should mainly be applied to the scalp. The lather that runs through when you rinse is usually enough to clean the lengths. Conditioner, mask and oil for dry hair should be concentrated on the mid-lengths and ends. This approach avoids weighing down the roots.

For a treatment designed for dry, brittle hair, look for a combination of humectants, such as glycerin, along with fatty substances and conditioning agents. Long hair can also benefit from an anti-split-end treatment designed to smooth the appearance of the ends, without expecting it to provide a permanent reconstruction.

2. Look at the proteins, oils and film-forming agents

Hydrolysed keratin, silk, collagen and certain amino acids are common in treatments for weakened hair. Camellia, argan, castor, marula and jojoba oils mainly help to nourish the fibre and improve its feel.

Silicones, such as dimethicone or amodimethicone, can make detangling easier and reduce the feeling of roughness. They aren’t necessarily a problem. However, if you’re looking for a repairing treatment without sulphates, check each formula carefully – the absence of sulphates doesn’t automatically mean silicones are absent too.

3. Consider your water and local habits

In areas where the water is very hard or heavily mineralised, deposits can leave hair rough and dull. A hair detox treatment for metals and minerals can complement your routine, especially before colouring or another chemical treatment. It doesn’t replace a regular shampoo and should be used according to the manufacturer’s instructions.

Finally, if you regularly use a hairdryer, straighteners or curling tongs, make sure you use a heat protectant and keep the temperature down. No treatment can fully compensate for exposure to heat that’s too high or too frequent.

FAQ on damaged hair care

What order should I follow for a repairing routine?

Start with shampoo, then apply conditioner to the lengths. Reserve the protein or nourishing mask for one or two uses a week, depending on how sensitive your hair is. Apply oil in small amounts to dry or damp hair, mainly on the ends.

How long do I need to use a treatment to see a difference?

Detangling and softness can improve from the very first application. Reducing breakage, however, depends on your styling habits, how often you wash and the initial condition of your hair. If your ends are very split, a treatment can improve their appearance, but it will never replace a trim.

Can I combine Japanese and Korean hair care products in the same routine?

Yes, as long as you don’t layer several rich or protein-heavy formulas on the same day. For example, you could use a gentle shampoo, a light conditioner and a targeted mask once a week. Always read the label, follow the instructions and stop using if irritation occurs.
