Shampoo or Conditioner First? The Order Actually Matters
It sounds like a trivial question, but the order you apply shampoo and conditioner actually changes the result you get.
The Standard Order
Shampoo first, conditioner second, is the order dermatologists and stylists recommend for most hair types. Shampoo opens the hair cuticle slightly to clean the scalp and strands and strip away oil and product buildup. Conditioner then smooths and closes that cuticle back down, sealing in moisture and making hair easier to detangle.
The Reverse Wash Method
Some people with fine or low-porosity hair try conditioning first, then following with a light shampoo. The idea is to avoid weighing hair down with conditioner while still getting some of its smoothing benefit. It can work well for fine hair prone to going flat, but it will not deep-clean the scalp as effectively.
What About Co-Washing?
Co-washing skips shampoo altogether in favour of a cleansing conditioner. It suits very curly or dry hair types that get stripped out easily by regular shampoo, but it is a poor fit for oily scalps or anyone using heavier styling products, since it will not remove buildup effectively.
The Practical Rule of Thumb
For most people, the standard order works best: shampoo focused on the scalp, conditioner focused on the mid-lengths and ends. Treat the reverse-wash and co-wash methods as exceptions for specific hair types, not the default everyone should switch to.

Frequently Asked Questions
What happens if you use conditioner before shampoo?
It can leave fine hair feeling lighter since less conditioner residue remains, but it will not clean the scalp as thoroughly as shampooing first.
Should conditioner go on the scalp or just the ends?
Mostly the mid-lengths and ends. Applying heavy conditioner directly to the scalp can leave hair looking greasy faster.
