(KGTV) - Does your hair really grow faster during the Summer months?

The evidence is shaky at best.

An expert says any increase in hair growth is marginal, maybe 10%.

She says the slight increase likely comes from a natural hormonal shift and an increase in UV exposure.

The best indication of how your hair will grow is your DNA, so check those old family photos.
