Hair Care Guide: How to Choose the Right Treatment for Your Needs

By Joybuy, our product expert | Updated 26 August 2026

Dry, brittle, lifeless hair? It's a struggle many of us know all too well. Faced with a jungle of products promising the world, it's easy to feel lost and empty your wallet for disappointing results. The real challenge isn't finding a hair treatment, but discovering the one that's truly right for your hair.

To avoid throwing your money away, here are the common traps to avoid:

  1. The "miracle ingredient" myth: Many brands hype up a "star" ingredient (a rare oil, for example) when its concentration is minuscule, lost in a sea of silicones that only mask the damage.
  2. The "all-in-one" product illusion: No, a single shampoo, even an excellent one, cannot single-handedly repair a distressed hair fibre. A truly effective dry or damaged hair routine relies on combining several complementary treatments.
  3. Confusing nutrition with repair: Applying an ultra-rich treatment to hair that primarily needs protein can weigh it down, and vice versa. The first step is always to make the right diagnosis.

Key Criteria for Choosing the Right Hair Care

To see things more clearly and make the right choice, focus on a few essential points. They will help you decipher labels and invest in products that actually deliver on their promises.

1. Identify the Main Need: Nutrition, Repair, or Strengthening?

The first step is to perform a simple diagnosis of your hair's condition.

  • Needs nutrition: Your hair is dry, dull, and rough to the touch but not necessarily brittle. It lacks lipids. Look for formulas rich in plant-based oils (argan oil for hair, coconut, shea) and hydrating agents. The goal: to restore softness and shine.
  • Needs repair: Your hair is porous, stretchy when wet, and dotted with brittle strands and split ends. It's suffering from damage (colouring, straightening, excessive heat...). It's crying out for proteins to rebuild its structure. Hair keratin, amino acids, and hydrolysed proteins are your best allies here. A good repairing shampoo or a damaged hair mask becomes essential.
  • Needs strengthening (anti-hair loss): Are you noticing a loss of density or more shedding than usual? A targeted anti-hair loss treatment will work directly on the hair bulb. In parallel, a hair supplement containing biotin, zinc, and selenium can support growth from the inside.

2. Build a Complete and Coherent Routine

A single product doesn't work miracles. For visible and lasting results, a multi-step routine is necessary.

  • Washing: Choose a shampoo suited to your scalp type and the needs of your lengths.
  • Deep conditioning: The damaged hair mask is the cornerstone of your routine. Apply it once or twice a week, carefully respecting the leave-in time to allow the active ingredients to penetrate the core of the hair fibre.
  • Daily care: A leave-in treatment protects hair from daily aggressors (heat, pollution), makes styling easier, and maintains hydration or protein levels throughout the day.

Hair Care: Your Frequently Asked Questions

What's the difference between a keratin mask and a hydrating mask?

To put it simply, a hydrating (or nourishing) mask is packed with lipids (oils, butters). It's perfect for dry hair that lacks softness and shine. Conversely, a keratin mask is a repairing treatment, loaded with proteins. Its purpose? To fill in the gaps in the fibre of damaged, brittle hair to strengthen it from the inside. Using the wrong mask can weigh your hair down or, worse, completely miss what it needs.

How often should I use a mask for damaged hair?

For very damaged hair, start with an application twice a week. As soon as you notice an improvement (less breakage, softer texture), switch to a maintenance routine of once a week. Be careful, though: an excess of protein masks can make hair stiff. The secret is to learn to "listen" to your hair and adjust the frequency accordingly.

Are hair supplements really useful?

Yes, hair supplements can be a real asset, especially if your diet isn't optimal or if you're going through a period of stress or fatigue. Actives like biotin (vitamin B8), zinc, and selenium are recognised for their role in maintaining normal hair. They work from the inside, at the root of the problem. However, they are no substitute for a balanced diet and a good hair care routine. And in cases of significant hair loss, the best course of action is always to consult a healthcare professional.
