This could be injurious to his brain!!
I was half expecting this.
My dad, trying to fight back his brains getting scrambled after the stroke, had a hard jolt trying to understand what happened to Natasha’s hair. Tasha, had dyed her hair blonde some time back. Over the last few months as the hair has grown, her strands are natural dark (from the root side) and then after about half length starts becoming blonde.
My dad’s relatively low exposure of dyeing hair entirely comprises of making the hair look dark again (from grey) but never from dark to any thing else.
As you see in the picture, he held her hair in his fingers for quite some time trying to investigate what was going on. He asked quite a few questions – much to Tasha’s merriment – and then gave up trying to understand it!!
