It all comes from your X chromosome (Picture: Getty)

Getting a bit smooth up top? Judging on how you feel about it, your mum is the one you should be blaming /thanking.

Researchers at the University of Edinburgh have found that men inherit most of their baldness genes from their mums side of the family.

For what is the largest ever analysis of hair loss, scientists looked at the DNA of 52,000 men.

They identified almost 300 genes that could contribute to male pattern baldness most of which come from the X chromosome.

Saskia Hagenaars, who jointly led the research, said: We identified hundreds of new genetic signals.

It was interesting to find that many of the genetics signals for male pattern baldness came from the X chromosome, which men inherit from their mothers.

Before this research, published in PLOS Genetics, scientists had only identified a handful of genes related to baldness.

The studys principle investigator, Dr Riccardo Marioni, added: We are still a long way from making an accurate prediction for an individuals hair loss pattern.

However, these results take us one step closer.

The findings pave the way for an improved understanding of the genetic causes of hair loss.
