Essential Hair & Scalp Care Science
Stop guessing what your hair needs. Get clarity on your unique scalp type, the correct washing routine, and why most internet hacks are just wasting your time.
**Are you washing your hair correctly for your scalp type?** I guide you on the ideal washing frequency for oily, dry, and combination scalps to avoid stripping natural oils or causing buildup. Using the right shampoo and technique makes all the difference.
**Here is a simple guide to identifying your scalp type.** I explain the characteristics of oily, dry, and normal scalps by observing how your hair and scalp feel a few hours after washing. Knowing your type is the first step to choosing the right products.
**Still have dandruff even after using an anti-dandruff shampoo? You might be using it wrong.** The key is to apply it to the scalp, massage it in, and leave it on for 10-15 minutes before rinsing. This allows the active ingredients to work effectively.
**I used to think air drying was the healthiest option, but a study proved me wrong.** Prolonged water exposure can damage the hair's inner structure. I explain how using a hairdryer on a cool setting at a distance of 15 cm can actually be less damaging than letting your hair air dry for a long time.
**Using the wrong hairbrush can cause breakage and frizz.** This is your ultimate guide to choosing the perfect brush. I recommend different brushes for thick, curly, fine, straight, and damaged hair, including wooden, boar bristle, and nylon bristle types.
About Essential Hair & Scalp Care
Most patients come to me confused because they are using an anti-dandruff shampoo, but their condition only gets worse. The secret is not just the product, it is the technique: you must massage the shampoo onto the scalp and let it sit for 10 to 15 minutes to allow the active ingredients to actually penetrate. If you just rinse it off immediately, you are essentially washing money down the drain.
Identify Your Scalp Type
You cannot fix a problem if you do not know the root cause. A simple test: press a tissue on your scalp a few hours after washing. If it picks up oil, you likely have an oily scalp. If it is dry, tight, or flaky, your scalp needs hydration, not more harsh treatments. Understanding your specific type—whether it is oily, dry, normal, or combination—is the first step in my diagnostic process.
Why Air Drying Can Be Damaging
We often think air drying is the healthiest option, but studies show that prolonged exposure to water can damage the inner structure of the hair shaft. This can cause the hair to lose strength and become frizzy. I recommend using a hairdryer on a cool setting, keeping the nozzle at least 15 cm away from your hair. It is counterintuitive, but it is often safer for your hair structure than leaving it damp for hours.
Choose the Right Tool
Using the wrong hairbrush is an easy way to cause breakage. For thick or curly hair, a wooden bristle brush is better for detangling without friction. If you have fine or straight hair, boar bristle brushes are excellent for distributing natural oils and adding shine. Do not just grab the first brush you see at the store.
