In an interview on DZMM's "Magandang Gabi Dok", Dr. Rica Mallari said it takes around three to five years for hair to grow fully.
After five years, the hair will die, and new hair will grow out from the same root.
Mallari added that 90% of a person's hair is continuously growing, with the other 10% falling out.
However, certain conditions can cause growing hair to die prematurely, causing hair fall.
"Kasi kapag nagbuntis, nanganak, kahit 'yung fever, minsan 'yung nag-grow pa, hindi na nag-gogrow, parang nawala 'yung balance sa body," Mallari said, adding that 40% of a person's hair can fall out after suffering from stress or illness.
Excessive hair fall usually stops after a few months, once a person's body has recovered from the imbalance.
The cycle of hair growth and hair fall may continue as long as the imbalance is not addressed.
In some cases, the roots also lessen in size, causing stunted hair growth, or even hair loss.
"Kapag nawala na 'yung root, hindi na tutubo ang buhok," Mallari said.
Mallari advised those suffering from excessive hair fall and hair loss to consult their doctors before taking any medication.
If hair fall is due to stress, or hormonal imbalance, addressing the imbalance can solve the problem.
"Mahirap talaga magpa-grow ng buhok," Mallari added.
