After a lifetime of believing my hair is poker straight it seems I might be wrong! I let it air fry the other day without brushing it when wet and there was a really slight wave. This morning after washing I didn’t brush it and scrunched in some Tresemme air dry curl cream and got the results in the photos! Is my hair actually a bit wavy? If it is what can I do to encourage the wave? I’ve spent nearly 40 years wishing for anything but straight hair and some waves would be amazing! Does anyone have any hints or tips?
