Nail fungus is something which affects millions of people throughout 
the world And can be a challenge to treat effectively. In fact there is 
estimated to be around 18% of the population at any given time will be 
suffering with or trying to treat a nail fungus infection.
It 
occurs when the fungus, called a dermatophyte, finds an entry point into
 the nail and then spreads and colonisers the nail bed. This process is 
known medically as Onychomycosis.
It can affect both the 
fingernails and toenails although an infection of the toenails is more 
common as our feet are generally hidden away from view and covered by 
shoes and socks which provide the damp dark and moist environment for 
which the fungus loves to grow.
Toenail fungal infections may 
start with a fungal infection of the web spaces between the toes called 
athletes foot, which then migrates to the nails. Fingernail fungal 
infections are typically introduced by using nail bars and beauty salons
 where the instruments and tools are not sterilised correctly, if at 
all.
Probably the worst thing about a fungal toenail infection is 
that the nail will eventually detach from the nail bed and drop off, 
although this is unlikely to be painful. However, most people are more 
embarrassed by the stages of deterioration before this happens, such as 
the yellow and brown discolouration and the thickening and disfigurement
 of the nail plate itself.
Many older people decide not to treat 
the fungal nail infection as it can be more trouble than it's worth, 
particularly if there is no pain, but if you are diabetic or suffering 
with circulatory disorders your doctor will want you to undergo a course
 of treatment because of other complications that can arise such as 
bacterial infections taking hold under the nail, which may lead to more 
serious problems for these types of patients.
For those that do decide to treat their infection there are a variety of ways to do it:
- Natural remedies
 - Over-the-counter medications
 - Prescribed medications
 - Laser treatments
 
The most common strain of nail (and skin) fungus is Trichophyton rubrum
 and whatever course of treatment you decide to take will need to 
specifically attack this organism. For natural remedies one of the best 
methods is to use 100% pure tea tree oil. Try to apply this directly 
between the nail plate and the nail bed so that it runs between the two 
attacking the fungus directly.
There are many over-the-counter 
preparations available from your pharmacist so it is always best to ask 
their advice. Many involve filing the nail down and applying a lacquer 
which contains an acid penetrates the nail reaching the fungus below. 
However, these may take a very long time and end up being ineffective, 
not least because the patient gives up halfway through.
Your 
doctor or podiatrist may be able to provide you with an oral anti-fungal
 medication which is taken generally over a period of six months but may
 lead to complications such as liver damage.
