Conditioner for hair: how to choose the right formula for your needs

A conditioner shouldn't be chosen solely for its scent or the promise on the bottle. A formula that's too rich can weigh down fine hair, while a treatment that's too light will leave dry hair difficult to detangle. British shoppers also have to navigate sometimes vague claims like "repair", "intense nutrition" or "professional effect".

Before you buy, three common pitfalls keep cropping up:

  • Confusing detangling with deep repair: a product can smooth the hair shaft to the touch without improving its condition long-term.
  • Relying only on the highlighted ingredients: the presence of argan oil, shea butter or proteins doesn't tell you whether the texture will suit your hair.
  • Overlooking the full ingredients list and format: silicones, fragrances, allergens, preservatives and the amount used per application all affect both the experience and the real cost of the product.

What to check before you buy

1. Choose a texture that suits your hair type

For dry, curly or very dehydrated hair, go for a creamy texture containing conditioning agents, glycerin, oils or plant butters. Fine hair will generally prefer a lightweight hydrating conditioner, applied only to the mid-lengths and ends.

Curly hair needs a detangling treatment that makes styling easier without breaking the curl's spring. The Avril conditioner for curly hair, for example, contains organic linseed oil and is listed as silicone-free on its product page.

2. Read the INCI list rather than the marketing promise

The ingredients list lets you check what the formula actually delivers:

  • Conditioning agents such as behentrimonium chloride or cetrimonium chloride make detangling easier.
  • Silicones like dimethicone or amodimethicone give a smooth, silky feel. However, they don't suit every hair care routine.
  • A silicone-free formula may appeal to those who want to limit certain film-forming agents, but it isn't automatically more effective.
  • Fragrances and allergens are worth considering if your scalp is reactive or if you have a known sensitivity.
  • Organic and vegan labels don't mean the same thing: the first mainly concerns certification and the origin of certain ingredients, while the second guarantees no animal-derived ingredients and, depending on the brand, comes with specific commitments.

3. Compare the size and leave-in time

A 200 ml bottle can work for occasional use or for trying a product. A 450 ml format is better value for a regular routine. Also check the leave-in time: some treatments rinse out after a few seconds, while a repairing conditioner for damaged hair needs two to three minutes.

To avoid waste, gently squeeze out excess water from your hair after shampooing, then apply a small amount to the mid-lengths and ends. Roots should generally be avoided unless stated otherwise.

Frequently asked questions about conditioner

Should you use conditioner every time you wash?

It depends on your hair type and the shampoo you use. Dry, long, curly or coloured hair can benefit from regular application. For fine hair, a small amount on the ends each time you wash may be enough. If your hair quickly looks flat or greasy, reduce the amount or use it less often.

How long should you leave a detangling treatment on?

A standard conditioner usually works in anything from a few tens of seconds to a few minutes. Follow the manufacturer's instructions. Leaving the product on for longer doesn't guarantee better results and can make rinsing more difficult.

Which conditioner should you choose for coloured hair?

Go for a formula designed specifically for coloured hair and check whether it contains any filters or agents intended to preserve shine. Klorane Protecting Conditioner with Pomegranate, for example, is listed as silicone-free and formulated with pomegranate extract. For a re-pigmenting treatment, Kemon Yo Cond Color System products deposit a temporary shade. However, it's best to test the product on a small strand before first use.
