Check out our step-by-step guide to how your shampoo cleanses and protects your hair to keep it clean and looking beautiful.
What makes your hair dirty?
Your skin produces the natural oil, sebum, which protects your hair and hair follicles.
While it’s really beneficial, it can also build up and leave your hair looking greasy.
Dust, pollen and dirt get attached to the oil too, contributing to the dull, oily look. Sebum is an oil, which means it’s hydrophobic –and if you’ve ever tried to mix oil and water, you know it just won’t work.
So when it comes to washing it off, water alone won’t do the job.
How shampoo works:
- Shampoo contains molecules called surfactants. These emulsify the sebum, allowing it to mix with water
- When you rinse, the water takes the emulsion with it, including all the dirt and grease
The more grease there is attached to the surfactant molecules, the less the shampoo will lather.
That’s why the first time you wash really dirty hair, you might not get a huge lather – but repeat it after rinsing and you’ll noticeyour lather is much bigger the second time around!
Some shampoos are specifically designed with extra ingredients – sometimes to give you a different sensation in the shower and othertimes to give you additional hair benefits.
- Itchy scalp shampoos often contain cooling agents like mint or eucalyptus.
- Different scents are added like Apple or Citrus Fresh for great-smelling hair.
- Anti-dandruff shampoos like our Classic Clean Shampoo contain agents like zinc pyrithione to fight dandruff and keep it from comingback.
Added moisturisers in shampoo
Some shampoos are formulated with moisturisers to condition and restore a protective coating on the hair.
