Why Most People Wash Long Hair Completely Wrong
Long hair ≠ short hair on top of more hair.
Sebum takes 3–5 days to travel from scalp to ends.
Washing daily strips the length while the scalp stays oily → dry, brittle ends + greasy roots.

The Science Behind Long Hair Product Selection
When choosing products for long hair, the goal is always to balance a clean scalp with moisture retention in the old, dry ends. For this reason, selecting the right formulation is crucial.
Focus on Amino Acids and Gentle Formulas: Look for shampoos with amino acid-based cleansers or gentle sulfate-free formulas. These are effective at removing buildup from the scalp without stripping the natural, necessary oils from the length.
Avoid Harsh Detergents: Products containing high levels of harsh detergents (like SLS) should be avoided entirely, as they accelerate dryness and damage the cuticle, leading to increased frizz and breakage in already fragile long ends.
For maximum length protection, always pair a clarifying shampoo (used bi-weekly) with a deeply hydrating, rich conditioner.

FAQ – Long Hair Washing Routine
How many times a week should you wash long hair?
2–4 times max. Most people with waist-length hair do 2–3.
Should you shampoo long hair twice?
Yes — first cleanse removes oil/buildup, second actually cleans.
Can I just rinse long hair with water?
Absolutely. Water-only rinse + conditioner refreshes 80% as well.
Why does my long hair feel dry after washing?
You’re either washing too often, using hot water, or applying shampoo to the ends.
