Dandruff Treatment, and Whether It Is Really Why Your Hair Is Falling

It is generally related to seborrhoeic dermatitis — an inflammatory response involving Malassezia, a yeast that lives on everyone's skin, together with scalp oil and individual susceptibility. It is not caused by poor hygiene, and washing more aggressively often makes it worse rather than better.

Not permanent hair loss, and this is the misunderstanding worth correcting. It does not cause pattern baldness. What it can do is increase shedding while the scalp is inflamed and itchy, partly through the inflammation itself and partly through scratching. That shedding usually recovers once the scalp settles.

Often because two separate things are happening at once. Dandruff is visible and itchy, so it gets the attention, while genuine pattern hair loss progresses quietly underneath. Treating the scalp will not address the pattern loss, and treating pattern loss will not stop the flaking. Both need identifying, which is what the examination is for.

They look similar and are treated almost oppositely. Dandruff usually produces larger, oilier, yellowish flakes on a scalp that may be red and itchy. A genuinely dry scalp produces smaller, drier, whiter flakes and is usually part of generally dry skin. Treating dandruff as dryness with heavy oils frequently makes it worse.

Several conditions present in a similar way and need distinguishing: scalp psoriasis, fungal infection of the scalp, contact dermatitis from a hair product, and in some cases inflammatory conditions that can scar. They are managed differently, which is the reason for examining a scalp rather than recommending a shampoo from a description.

Medicated shampoos are the mainstay, and the active ingredient matters more than the brand. Antifungal preparations, zinc-based and selenium-based preparations, tar preparations and keratolytics that lift scale are the usual categories, sometimes rotated. Where there is significant inflammation, a prescribed anti-inflammatory preparation may be added for a period. What suits your scalp is decided on examination.

Most people use them wrongly. The active ingredient needs contact time on the scalp rather than on the hair, so it is worked into the scalp and left for the period stated on the product before rinsing. Applying it like ordinary shampoo and rinsing straight away is the most common reason a perfectly good product appears not to work.

Usually, yes. Seborrhoeic dermatitis is a recurring condition that is controlled rather than cured. Most people find it settles with treatment and then needs occasional maintenance, often flaring in particular seasons or during periods of stress. Expecting control rather than a permanent cure is the realistic frame.

Many people notice flares during stressful periods, and seasonal change is a common trigger too. That does not make it a psychological condition, and it does not mean it will resolve by relaxing. It is a reason to have a maintenance plan for the periods when it tends to return.

No. The yeast involved lives on everyone's skin. What differs is the individual response to it, which is why one person in a household has it and another does not.

Usually the opposite. Regular washing helps by reducing the oil that the process feeds on. What does not help is aggressive scrubbing, very hot water, or heavy oil applications left on an inflamed scalp, all of which are common self-treatments that make things worse.

Some are harmless, some are actively unhelpful, and heavy oiling of an already oily inflamed scalp falls into the second category more often than people expect. If something has genuinely helped you, say so at consultation and it can be worked around. What is not sensible is months of home treatment while a scalp condition persists or hair loss progresses.

The scalp condition is treated and controlled before any surgery. Operating on an inflamed scalp is not sensible, and healing is better on a settled one. It is a delay rather than an exclusion.

If it is not responding to a properly used medicated shampoo, if the scalp is very red, sore or bleeding, if there are well-defined thick plaques, if there are patches of actual hair loss, or if you are also losing hair. Any of those warrants an examination rather than another shampoo.
