Nizoral
There are many thoughts on what causes dandruff. There is however, only one real answer. It is now known that dandruff is primarily caused by a fungus known as Pityrosporum ovale (P. ovale). Scientists may also call it malassezia furfur.
Before you recoil in disbelief, you should know that this fungus is a naturally occurring organism found on everybody’s scalp and in most cases poses no problem at all.
However, under certain circumstances, P. Ovale can proliferate, irritating the scalp and depleting it of it’s nutrients. When this occurs, dead cells are shed from the scalp faster – flaking and itching are the result.
This condition is known as dandruff.
What makes Nizoral unsurpassed as a dandruff treatment?
Put simply, Nizoral treats the cause of dandruff – excess of P. ovale found on your scalp. Whilst some other treatments are busy treating only the symptoms, Nizoral goes to work on the cause.
In fact, the active ingredient in Nizoral has been clinically proven to be your best defence against P. Ovale. This gentle, active ingredient also binds to the natural protein in your hair called keratin. So it keeps working for days after you have stepped out of the shower.
The importance of binding with keratin.
Most active ingredients found in other dandruff shampoos lack the ability to bind with the keratin found in your hair. Unfortunately, this means that when rinsing the shampoo out the active ingredient is also going down the drain.
Even worse, this allows the P.Ovale to re-colonise the scalp. That is why when using these shampoos you need to wash your hair on a daily basis.
Thankfully, Nizoral has a strong affinity for keratin and actually binds with the scalp and hair shafts. Therefore, you only have to use Nizoral twice a week. Continued use just twice a week will keep dandruff from returning.
The dandruff shampoo that really shines.
Nizoral really is a gentle giant. It’s tough on the cause of dandruff, yet leaves your hair looking the way you want it to look. More importantly, it helps keep your hair healthy!
Dandruff is caused by micro-organism called pityrosporum-ovle which are present in every body's scalp. Symptoms of dandruff get aggravated when exposed to dust, UV light, harsh chemical based shampoo, hair dyes etc., this results in increase in number of microbes which causes unhealthy residue over the scalp which leads to dandruff, which is the cause of unhealthy scalp results in unhealthy, lifeless hair and may result in excessive loss of hair too.
Contrary to popular notions, dandruff is usually a result of too much oiliness of the skin and scalp rather than dryness. While mild dandruff may be caused by overactive oil glands, recent evidence suggests that the more severe dandruff associated with seborrheic dermatitis may be caused by an overabundance of Pityrosporum ovale, a yeast-like organism found on healthy scalp in low numbers. With the increased scaling and oiliness of seborrheic dermatitis, these yeast organisms thrive and multiply, aggravating inflammation and scaling.
Seasonal changes, stress, and certain diseases seem to affect seborrheic dermatitis. The cold, dry air of fall and winter often triggers a flare-up. Emotional stress can worsen the condition as well. Skin cells that grow and die off too fast are the cause of dandruff, but doctors do not know why this happens. Some people with severe flaking have overactive sebaceous glands (whose task is to lubricate the skin with oils); others have an elevated level of the fungus Pityrosporum ovale, which is present in most people but to excess in dandruff sufferers. Other causative factors include family history, food allergies, excessive sweating, use of alkaline soaps, yeast infections, and stress. Even the season of the year can contribute to the problem: Cold, dry winters are notorious for bringing on dandruff or making it worse.
If dandruff flakes are greasy and yellow, the probable cause is the skin condition known as seborrheic dermatitis; dry, thick lesions consisting of large, silvery scales may be traced to the less common psoriasis of the scalp. These forms of dandruff—as well as the run-of-the-mill variety—become a hazard only if you scratch to the point of causing breaks in the skin, which can place you at greater risk for infections, particularly from staph and strep bacteria.
