PROVEN REMEDIES WORTH TRYING

Hedrin Once Spray Gel (£5.99, LloydsPharmacy) kills head lice and eggs in one 15-minute treatment. It works by physically smothering the lice and contains penetrol, which helps the product to penetrate louse eggs in order to kill them.

Medical Herbalist and clinician Dr Chris Etheridge recommends Puressentiel Lice Repellent Spray (£9.99, Boots) and Anti-Lice Treatment (£12.99) “clinically proven to eliminate lice, nits and larvae in 10■■minutes, thanks to a combination of six vegetable oils and four essential oils”. Neither contain pesticides, dimeticone, silicone or neurotoxic repellents.
