Among the many labels we can find on our hair and beauty products are ‘organic’, ‘natural’, ‘clean’ and ‘cruelty free’. These reflect the demands of consumers, who have high expectations not only about what products can do for them, but also the suitability for their lifestyles. That’s why it’s vital for salon and barbershop staff to know what’s in products, what the ingredients do and what wider effects they can have – both for their own benefit and that of their clients.

‘Clients want to know not just if their product smells nice, but also what’s actually in it,’ says David Antony, director of the David Antony salon in Southsea.
