In the fast-paced world of hair trends driven by platforms like TikTok, one aspect of style remains timeless: healthy, shiny, and vibrant hair. Achieving and maintaining healthy hair, however, can be more challenging than it seems, with factors like genetics, hormones, and environmental influences playing a significant role. The foundation for healthy hair lies in having a healthy scalp.
If you’re feeling bewildered about how to nurture your hair’s well-being, you’re not alone. To shed light on hair and scalp health, we turn to a dermatologist to answer some of the most common questions.
What Causes Dandruff, and How Can You Eliminate It Quickly?
Before addressing dandruff, it’s crucial to understand its root cause. Typically, dandruff results from an imbalanced scalp microbiome, as explained by Dr. Leona Yip, a dermatologist and fellow of The Australasian College of Dermatologists.
“Dandruff is not an infection you catch,” Dr. Yip clarifies. “It is caused by an imbalance in the scalp microbiome and an overgrowth of yeast. It’s also related to the production of scalp sebum (oil) in which yeast thrives. The skin responds by shedding more skin cells, leading to visible scalp flaking, which we recognize as dandruff.”
Typical dandruff presents as white flakes without apparent redness, itchiness, or irritation of the scalp. If left untreated, it can progress to a more severe form called seborrheic dermatitis, characterized by thicker, yellowish, and greasy flakes. If your dandruff takes on this latter appearance, it’s advisable to consult with your GP or dermatologist for a proper diagnosis and treatment plan.
For most individuals, an anti-dandruff shampoo containing active ingredients like selenium disulphide can effectively combat dandruff. An example is the Dercos Anti-Dandruff DS Shampoo for Normal to Oily Hair. Dr. Yip notes that ingredients like selenium disulfide can restore scalp microbiome balance. This particular formula can eliminate up to 100% of dandruff after the first use and rebalance the scalp microbiome in just four weeks. It also provides up to six weeks of anti-relapse action, keeping dandruff at bay for an extended period.
Tip: When using anti-dandruff shampoo, leave it on for a few minutes to ensure it has sufficient time to work its magic.
Is Hair Thinning Normal?
Hair loss can be attributed to various factors, with stress, genetics, and hormones being among the most common culprits. It’s important to remember that hair growth occurs in four stages: growth, rest, shedding, and regeneration. When this process is disrupted by health or lifestyle factors, such as a stressful event or a significant dietary change, it may take up to three months for recovery.
If you notice significant hair loss, it’s advisable to consult with a healthcare professional to rule out any underlying issues.
How Can You Prevent Flat and Limp Hair?
Flat, lifeless hair often results from an accumulation of oil and heavy styling products weighing down the strands. To prevent build-up, wash your hair regularly and avoid deep-moisturizing conditioners that can leave your hair looking greasy and flat. Consider incorporating an anti-dandruff shampoo into your routine to maintain scalp microbiome balance, which can contribute to healthy hair growth.
If your hair naturally lacks volume, consult with your hairstylist to discuss strategic hairstyles that create the illusion of more volume. Layers and balayage, for example, can add dimension and texture to fine hair.
The Key Lies in Scalp Health
In summary, the health of your hair is closely tied to the condition of your scalp. An unhealthy or inflamed scalp can lead to dandruff, increased hair shedding, and hindered hair growth.
Look out for signs of a scalp in need of extra care, including:
- Burning, itchiness, or discomfort
- Redness, flaking, or sun damage
- Excessive hair shedding
If you notice any of the above or discover new or enlarging scalp lumps, it’s essential to refrain from self-diagnosis and schedule an appointment with a GP or dermatologist for a professional evaluation.
