The oiliness experienced when you have dandruff is caused by an overgrowth of yeast. “Yeasts naturally live on your scalp, and usually do not cause any problems. However, itching and flaking can occur when an overgrowth of yeast causes your scalp’s microbiome to become imbalanced. However, some people are simply sensitive to normal levels of these yeasts on their scalp,” says Anabel.
“It is difficult to differentiate between dandruff and dry scalps, however, the best way to do this is to think what may have caused this dryness to the scalp,” says Stephanie. “Is it an allergic reaction to something you have used, or have you been using products that are drying out your hair and scalp recently? If you’ve answered yes, then it is probably a dry scalp,” she adds.
“If your hair is a bit greasy despite the flakes and is there all the time, then it is likely you are suffering from dandruff. If you are still not sure then use a dandruff shampoo for a while, like Nizoral (£9.30), and see if it alleviates the symptoms. If it is dandruff, then the ketaconazole (an anti-fungal ingredient) in Nizoral will do its job,” says Stephanie.
Is a flaky scalp different to dandruff?
A flaky scalp can be a symptom of dandruff, but it’s also a symptom of dry scalps, although they’re caused by different reasons. “With a dry, flaky scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed,” explains Stephanie.
“A flaky scalp can also be caused by other scalp conditions, such as tinea capitis (a highly infectious fungal infection of the scalp, also called scalp ringworm), allergic contact dermatitis (a reaction to products used on the scalp, such as hair dye, hairspray, hair gel or mousse), or psoriasis (a skin condition that causes red or silvery scales that are adherent to the scalp,) Stephanie clarifies.
Why does a dry scalp cause itchiness?
“A dry scalp is irritated and, as such, causes itchiness. Scalp issues such as seborrhoeic dermatitis can cause low-grade inflammation and shedding, which in turn causes itchiness,” says Stephanie.
What are the best ways to treat a dry scalp?
Identify the cause
“To deal with a dry scalp you need to identify the cause of it first. We have enough sebaceous glands on our scalp to keep the scalp lubricated, so if the scalp is dry, then there is most probably an underlying cause,” says Stephanie. “Some causes could be an allergic reaction to a product, or even washing your hair too often with a poorly formulated harsh shampoo,” she adds.
Try gently exfoliation
As with dry skin elsewhere on your body, a combination of gentle exfoliation and hydration can help. “Try a daily re-hydrating scalp toner containing ingredients such as sodium salicylate – an anti-inflammatory and anti-irritant active that helps to soothe the scalp,” says Anabel, such as Philip Kingsley’s Stimulating Daily Scalp Toner (£19.10).
Seek out soothing ingredients
“Some ways to address a dry scalp are by using something soothing like aloe vera gel directly on the scalp [try Aloe Pura Aloe Vera Gel, £6.49] or a hydrosol like rosewater [try Heritage Store Rosewater & Glycerin mist, £7.99],” says Stephanie
Use a nourishing oil
“A hot oil treatment, such as coconut oil and jojoba oil, just before you are going to wash your hair could go a long way as well to help rebalance the scalp,” Stephanie says.
Apply a scalp mask
“Twice weekly, apply a moisturising scalp mask containing ingredients such as aloe vera, and mild exfoliants, such as betaine salicylate,” Anabel says.
Drink plenty of water
Another tip? “hydrate from within i.e. drink enough water,” says Anabel.
