Not super intense biking, but my friend and I are going today, and biking to a local park and there will be cute boys. So how should wear my hair and do my makeup? (yes, I do plan on wearing a helmet )
Umm, well you should straighten your hair and put it in a pony, and do some light makeup like mascara, powder, eyeliner, and blush...I think that would look very cute(;
And if i were you, i wouldnt wear a helmet; but thats just me.
For makeup I'd stick with a tinted moisturizer with spf 15+, maybe mascara if you're not afraid of it running if it gets too hot, and lipstick. It's easy to reapply and an easy way to add color to your face and look put together. For hair I would go with braids because they're easy to wear with a helmet and when you take the helmet off your hair will still look ok.
Have fun on your bike ride, hope this helps a little bit.
