Dandruff Demystified: What Is It?
Dandruff is a scalp ailment consisting of white/or yellowish flakes of dead skin that slough off the scalp. Dandruff may arise from different conditions, the most common ones being:
Dry Skin: One of the most common causes of dandruff is dry skin; this is especially the case during cold weather when heating in your home can dry out your scalp.Â
Seborrheic Dermatitis: A type of dermatitis characterized by red, greasy lesions that are flaky and covered in white/yellow scale; this commonly occurs on the scalp, behind the ears, in the study area on the scalp, the eyebrows, cheeks, and around the nose.
Fungi (Malassezia): This is ya east that lives on the scalp. Although it lives on the scalp naturally, it’s possible for it to grow too much and cause irritation that leads to excessive shedding of skin.
Poor Hair Hygiene: Poor hair hygiene that leads to infrequently washing your hair can lead to grease, dirt, and dead skin not shedding, leading to dandruff.
Product Buildup: Many hair care products leave residue on the scalp, and this can lead to flakes and irritation of the scalp.
Diet and Lifestyle Factors: Deficiencies, stress, and hormones can also trigger or worsen dandruff.
Does Dandruff Contribute to Hair Loss?
Dandruff does not inherently cause hair loss, but it can be a contributing factor to certain problems that result in hair loss. Here are five possible ways;
1. Inflammation and irritation on the scalp
Dandruff can develop itchy spots and inflammation which creates excessive scratching or aggressive rubbing of the scalp. Frequent scratching can weaken the hair follicles which could cause damage to the hair, or cause hair to fall out.Â
2. Clogged hair follicles
The combination of the excess dandruff flakes and sebum (natural oil from the scalp) can clog hair follicles, which can restrict hair growth for a surprisingly long time. Dandruff also may contribute to conditions in which you may have thinner hair.
3. Weakening of the hair strands
Severe dandruff often called Seborrheic dermatitis results in increased oil and irritation that leads to the majority of hair roots becoming weaker which causes hair to fall out.
4. Fungal overgrowth (Malassezia)
An overgrowth of the Malassezia yeast becomes irritating to the skin and can result in excessive shedding. If not treated, this could lead to temporary hair loss due to excessive shedding.
5. Underlying health issues
Dandruff can also be a sign of another health issue, such as psoriasis or eczema, or due to hormonal changes, which can all lead to hair loss.
