At Charleston Head Spa, we love learning from our community. Recently, we asked our Instagram audience of over 36,000 followers a simple question:
Do you use dry shampoo more than twice a week?
The results were eye-opening. Out of nearly 500 votes, 69% said no, 29% said yes, and
a small 2% admitted to using it even more often.
This tells us that while the majority of people limit their use, a significant number rely on dry shampoo as part of their weekly routine. And that got us thinking: what is dry shampoo really doing to your scalp and hair health?

What Is Dry Shampoo, Really?
Dry shampoo is a product designed to absorb oil and refresh hair between washes. Most formulas rely on starches, clays, or alcohols to soak up excess sebum, leaving your roots looking less greasy and adding a bit of volume.
It’s a lifesaver for busy mornings, travel days, or when you want to stretch your style an extra day. But here’s the truth: dry shampoo does not actually clean your scalp. It masks oil and buildup rather than removing it. And over time, this can create bigger problems.
The Hidden Risks of Overusing Dry Shampoo on Scalp Health
Clogged Hair Follicles Just like pores on your face can get clogged with makeup and oil, your scalp pores can get clogged with dry shampoo particles, sebum, and product residue. This buildup sits around the follicle and can interfere with healthy hair growth.
Strangulated Follicles and Thinning Hair When buildup hardens around the follicle, it can actually suffocate the hair strand. This is one of the reasons why frequent dry shampoo use has been linked to hair thinning and even hair shedding in some people.
Scalp Irritation Ingredients like alcohols, starch, and fragrance can dry out your scalp, leading to itchiness, redness, and flakes. If you’ve noticed your scalp feeling tight or uncomfortable, overusing dry shampoo may be a culprit.
Fungal Overgrowth A scalp that’s never properly cleansed can become a breeding ground for yeast and fungi. This is the same reason dermatologists caution against going to bed with wet roots — moisture and buildup create the perfect environment for irritation.

Dirty Scalp
What We See at Charleston Head Spa
As head spa specialists, we see scalp buildup every single day. When clients come in, we often find layers of residue not just from dry shampoo, but from styling products, conditioners, and even hard water.
The buildup can be so stubborn that it takes a full hour of our signature head spa treatment to gently exfoliate and deeply cleanse the scalp. Using our custom protocols and products, we’re able to break down that barrier so the scalp can breathe again. Clients often tell us that their head feels lighter, their hair feels cleaner than it ever has before, and many report seeing fuller, thicker growth over time once their follicles are no longer suffocated by buildup.
It’s Not Just Dry Shampoo
While dry shampoo often gets the spotlight, it’s important to remember that all hair products can contribute to buildup. Leave-in creams, hairsprays, oils, serums, and even some shampoos and conditioners can leave residue if not properly washed out.
Think about it like this: if you applied moisturizer and sunscreen to your face every day without ever washing it off, your pores would clog. The scalp is skin too, and it requires the same level of care.
What the Research Says
A 2020 article in the Journal of Cosmetic Dermatology highlighted that excess buildup from hair products can lead to scalp folliculitis (inflammation of the hair follicles) and worsening hair shedding.
Dermatologists at the Cleveland Clinic have noted that using dry shampoo more than two times a week increases the risk of buildup, irritation, and long-term scalp imbalance.
Trichologists (hair and scalp specialists) often stress that a healthy scalp is the foundation of healthy hair. When follicles are blocked, hair struggles to grow at its full potential.
How to Use Dry Shampoo Safely
We’re not here to tell you to throw away your dry shampoo. Like most things, moderation is key. Here are a few tips:
Limit use to 1–2 times per week. Try to keep it as a backup, not a replacement for washing.
Apply only to the roots. Don’t spray it all over your hair — keep it focused on the scalp area where oil collects.
Wash thoroughly. Use a clarifying or purifying shampoo once a week to remove buildup.
Exfoliate your scalp. Just like your skin, your scalp benefits from gentle exfoliation. Scalp scrubs, brushes, or professional treatments can help.
Listen to your scalp. If you notice itching, flakes, or excess shedding, it may be time to cut back.
Why Professional Scalp Care Matters
At Charleston Head Spa, we’ve developed protocols that go beyond what you can do at home. Our treatments include:
Scalp analysis: We use tools to see exactly what’s happening at the follicle level.
Exfoliation: Gentle but effective techniques to remove buildup.
Deep cleansing: Milbon shampoos and custom scalp scrubs to reset your scalp.
Relaxation: A full spa experience that leaves your whole body feeling lighter, not just your scalp.
After just one session, clients often notice their hair feels softer and cleaner for longer. Over time, they may see thicker, healthier hair growth — something we’ve observed with many of our regulars.

What Our Poll Taught Us
Seeing that nearly a third of our audience uses dry shampoo more than twice a week tells us something important: people are looking for quick solutions in their hair routine. But quick fixes can create long-term problems if the scalp isn’t cared for properly.
That’s why we’re passionate about educating our community. Whether it’s through Instagram polls, in-depth blogs like this one, or one-on-one consultations at the spa, we want people to understand that scalp care is hair care.
Takeaway
Dry shampoo isn’t the enemy, but overuse can compromise your scalp health and hair growth. If you’re relying on it multiple times a week, it might be time to reset your scalp.
Charleston Head Spa is here to help you remove buildup, nourish your follicles, and restore your scalp to its healthiest state. With regular treatments, you’ll not only feel more relaxed, but you’ll also give your hair the best chance to grow thick, full, and beautiful.
