Hi {{first_name}}
Welcome to the Skin Deep & Unfiltered newsletter—your no-BS guide to all things skincare, hair, and wellness, straight from your favorite dermatologists.
This week on the podcast, we’re tackling one of the most misunderstood topics in beauty: haircare. From shampooing myths to the right way to use heat tools, we’re setting the record straight on the biggest hair lies that could be wrecking your strands.
Here’s a sneak peek into just a few of the tips we shared in this week’s episode:
✔️ Why over-washing your hair is making it more greasy (yes, really)
✔️ The truth about air-drying vs. heat styling (spoiler: it’s not what you think)
✔️ How to actually get stronger, healthier hair without wasting money on gimmicks
Let’s get into it.
1. OVER-WASHING YOUR HAIR? Here’s Why It’s Making Things Worse.
If you’ve ever thought, "My hair gets greasy so fast, I have to wash it every day!"—we get it. But here’s the kicker: washing too often can actually make your scalp produce more oil.
When you shampoo every day with a harsh cleanser, you strip away your scalp’s natural oils. Your body, thinking it needs to compensate, goes into overdrive—producing even more oil to make up for what was lost. The result? You’re stuck in a cycle of greasy roots and dry ends.
What to do instead:
✔️ Find your sweet spot: Most people do best washing 2-3 times a week. If you have very fine, oily hair, every other day may be ideal.
✔️ Use a gentle, sulfate-free shampoo: This cleans without over-drying your scalp.
✔️ Try dry shampoo in between washes: This helps absorb oil and add volume without stripping your hair.
Bottom line: Less washing = less oil production over time. Give your scalp a chance to balance itself out!
2. HEAT STYLING VS. AIR-DRYING: Which One Is Actually Better?
We’ve all heard it: "Let your hair air-dry! Heat styling is bad for your hair!" But is it really that simple?
Not exactly. While excessive heat can cause damage, air-drying isn’t always the better option. Leaving your hair wet for too long can cause hygral fatigue, a condition where the hair cuticle swells and weakens over time. If your hair takes hours to dry naturally, you might actually be causing more breakage than if you just used a blow dryer (the right way).
What to do instead:
✔️ Use a heat protectant. If you’re using a dryer, flat iron, or curling wand, this is non-negotiable.
✔️ Keep the heat low. Blow-dry on a low or medium setting, and avoid direct heat on the highest setting.
✔️ Diffuse or rough-dry instead of blasting high heat. For curly or wavy hair, a diffuser can help dry your hair with minimal frizz.
So no, heat styling isn’t the enemy—it’s how you use it that matters.
3. WANT STRONGER, HEALTHIER HAIR? Start with Your Scalp.
Most people focus on their strands when trying to fix their hair, but the secret to healthier, shinier locks starts at the scalp. Think of your scalp like the soil in a garden—if it’s not healthy, your hair won’t be either.
A neglected scalp can lead to buildup, irritation, and even weaker hair growth over time. And if you’re dealing with flakes, itchiness, or slow-growing hair, this could be your sign to start taking better care of your scalp.
How to show your scalp some love:
✔️ Exfoliate once a week: A gentle scalp scrub or a shampoo with salicylic acid helps remove product buildup and dead skin.
✔️ Massage your scalp: This increases circulation and encourages healthy hair growth.
✔️ Don’t skip conditioner: Even if you have an oily scalp, your ends still need hydration.
A healthy scalp = healthy hair. Start there, and your strands will thank you.
