Minoxidil & Hair Growth.
How does it work?
Minoxidil solution dilates small blood
vessels. When applied to the affected areas of the scalp twice daily it has
been shown to stimulate Hair Regrowth probably by enhancing cell proliferation.
It is possible it also has an effect on the immune cells in the hair follicle. Increased
hair growth is seen after approximately 4 months of treatment. Generally hair
growth is thinner and finer than the original hair.
What are the side effects of minoxidil
solution/
Local irritation may occur, most often
resulting in irching or stinging. Contact allergy to minoxidil or propylene
glycol (the main component of the solution) occurs rarely, and results in
dermatitis. Unwanted hair growth might occur ( hypertrichosis), for example if
the solution is dripped onto the forehead. Internal effects are not likely as
there is minimal absorption into the system. However, hair growth in distant
sites such as the arms, chest and lower back has occasionally been reported
when the 5% solution has been used.
Minoxidil is best avoided during
pregnancy and breastfeeding (Pregnancy Category C, i.e., Drugs that, owing to
their pharmacological effects, have caused or maybe suspected of causing
harmful effects on the human fetus or neonate without causing malformations.
These effects may be reversible.)
