What is a pre-wash oil?
A hair oil that you apply to dry hair before shampooing — lengths and ends, and optionally the scalp. It works for 30 minutes to overnight and is rinsed out during your next wash. Unlike a leave-in oil (which stays in the hair), pre-wash oil leaves no residue — you get the care without the heavy look.
Application
- Apply Pre-Wash Oil to dry hair—lengths and ends, optionally massage into the scalp
- Leave on for at least 30 minutes, or optionally overnight
- Tip: Wrap hair in a towel or shower cap to retain heat
- When washing, shampoo twice—the first time the shampoo binds to the oil, the second time it cleanses thoroughly
- Follow with regular conditioner
- Once a week is sufficient for most people
FAQ: Hair Oil & Hair Treatment
Which HAIR SYRUP for which hair type?
To start with: Original (all-rounder). For very damaged hair: Rapunzel or Superfoods. For an itchy scalp: Mint Condition. For dull hair: Vitamin C Me or Lemon-Aid (clarifying).
How long should you leave it on?
At least 30 minutes, preferably 1–2 hours, or optionally overnight. Use an old pillowcase or towel overnight—the oil can seep through.
Pre-wash oil or leave-in treatment?
Pre-wash oil is rinsed out and leaves no residue. Leave-in treatment stays in the hair—good for styling, but can weigh hair down. HAIR SYRUP is a pre-wash, KUNDAL Treatment is a leave-in.
Are the products vegan?
HAIR SYRUP is entirely vegan and cruelty-free, made in the UK.
How long does a bottle of HAIR SYRUP last?
A 100 ml bottle typically lasts 8–12 weeks with weekly use—one application requires about 5–10 ml, depending on hair length.
