If you’re noticing flakes, itchiness, or hair that never quite feels clean, you’re not alone. One of the most common concerns we see in the salon is scalp health — and one of the biggest misconceptions is assuming all flakes mean dry scalp.
In reality, flakes are often caused by product buildup, not dryness. Knowing the difference matters, because treating the wrong issue can actually make things worse.
What Is Product Buildup?
Product buildup occurs when styling products, dry shampoo, oils, and even shampoo residue accumulate on the scalp over time. This buildup can block the scalp, weigh hair down, and prevent shampoo from properly cleansing.
Signs of Product Buildup
Small flakes with little to no itch
Hair that never feels fully clean
Shampoo that does not lather well
Hair feels heavy, coated, or dull
If your shampoo does not lather the first time you wash, that is often a sign of buildup.
What Is Dry Scalp?
Dry scalp is a skin condition caused by a lack of moisture. It is more common during colder months and in dry indoor environments, and it requires a very different approach than buildup.
Signs of Dry Scalp
Itchiness or irritation
Redness or sensitivity
Dry or scaly flakes
Tight or uncomfortable feeling
Dry scalp is not caused by dirt or product — it is a hydration issue.
Why Treating the Right Issue Matters
Using hydrating products on buildup can trap residue on the scalp.Using clarifying products on a dry scalp can increase irritation.
The right treatment depends on what your scalp actually needs.
What to Do for Product Buildup
Use a detox or clarifying shampoo once a week to reset the scalp.
How to use it correctly:
Shampoo once
If it does not lather, shampoo a second time
Follow with your regular shampoo and conditioner
Recommended clarifying shampoos:
L’Elegance Collection Clean Slate
Kevin Murphy Maxi Wash
What to Do for Dry Scalp
Dry scalp benefits from gentle exfoliation and calming, hydrating formulas rather than harsh cleansing.
Recommended options:
Neuma ReNeu for gentle exfoliation
Maria Nila Head & Heal regimen for soothing and hydration
If You Have Psoriasis
RPM Treatment Shampoo & Conditioner may be recommended
Psoriasis should always be diagnosed by a medical professional before treatment
Seasonal Scalp & Hair Reminder
It is completely normal for hair and scalp to feel drier this time of year due to cold outdoor air and dry indoor heat. One important habit to avoid during this season is going to bed with wet hair, as moisture sitting on the scalp overnight can contribute to irritation and imbalance.
When in Doubt, Ask a Professional
A healthy scalp is the foundation of healthy hair. If you are unsure whether you are dealing with dry scalp or product buildup, a professional scalp analysis can help determine the best treatment and home care routine for long-term results.
If flakes, itch, or buildup are holding your hair back, talk to your stylist at your next L’Elegance appointment.
