My hair normally gets quite puffy after washing, especially around the ends. Since using this treatment it looks much sleeker and takes less time to style in the morning.
My hair tends to go frizzy very quickly in humid weather, so I wanted something that would help without making it look flat. This did exactly that. It looks smoother but still natural.
I have thick, wavy hair and usually spend ages trying to make it look smooth. After using this, it dries much better on its own and looks far less frizzy throughout the day.

It's suitable for all hair types, including color-treated hair. For the best and safest results, do a skin test first, wear gloves, apply in a well-ventilated room, keep it off your scalp and avoid eye contact.
