- A healthy scalp is the foundation of healthy hair. Choosing the right shampoo involves more than fragrance, price, or brand—it depends on the formulation and ingredients that support scalp health.
- A good shampoo should effectively cleanse while maintaining scalp balance. It should remove excess oil, dirt, and buildup without causing excessive dryness, irritation, or disrupting the scalp’s natural barrier.
- Be mindful of certain ingredients that may not suit your scalp. Common ingredients to watch include SLS/SLES, parabens, alcohol, and dimethicone.
- Proper washing techniques also matter. Use lukewarm water, massage gently with your fingertips, and allow the shampoo enough contact time before rinsing to maximize cleansing benefits.

When selecting a shampoo, many people focus on factors such as fragrance, price, or brand. However, the formulation and ingredients of a shampoo can play an important role in maintaining a healthy scalp and hair.
Healthy hair begins with a healthy scalp. Dermatologists, trichologists, and other hair care professionals generally agree that proper scalp care forms the foundation of healthy hair growth.
The primary function of a shampoo is to cleanse the scalp and hair by removing excess sebum, dead skin cells, sweat, environmental pollutants, and product buildup. Beyond cleansing, choosing a well-formulated shampoo can help maintain a balanced scalp environment. Some shampoos are formulated with milder cleansing agents and ingredients that support the scalp’s natural barrier, reducing the likelihood of irritation and inflammation while promoting healthier hair follicles.
Scalp inflammation is an important consideration because it can affect the normal hair growth cycle. Persistent inflammation may disrupt the hair follicle’s ability to remain in its active growth phase, contribute to increased hair shedding, and reduce the delivery of oxygen and nutrients needed for healthy hair growth. Over time, unmanaged inflammation may increase the risk of hair thinning.
Although shampoo alone cannot prevent or treat every form of hair loss, selecting an appropriate one is an important component of a comprehensive scalp care routine.
So what makes a good shampoo?
Ingredients to Avoid in Your Shampoo
First, let’s look at some common ingredients to avoid in your shampoo.
1. Sodium Lauryl Sulfate (SLS) / Sodium Laureth Sulfate (SLES)
Both sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), commonly referred to as a sulfate, are surfactants used in many shampoos to create a rich lather and effectively remove oil and debris from the scalp and hair. While SLS/SLES are effective cleansers, it can be harsh, particularly for those with sensitive, dry, or irritated scalps. Frequent use can strip away the scalp’s natural oils and contribute to dryness or irritation.
2. Parabens
Parabens are preservatives commonly used to extend the shelf life of cosmetic and personal care products by preventing the growth of bacteria and fungi. Although regulatory authorities consider approved parabens safe at permitted concentrations, some individuals with sensitive skin or existing scalp conditions may experience irritation. Common parabens include methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and isobutylparaben.
3. Ethanol (Alcohol)
Ethanol, sometimes listed simply as alcohol, may be included in shampoo formulations as a solvent or to help combine water- and oil-based ingredients. In higher concentrations or with frequent use, it can contribute to scalp dryness by increasing moisture loss. For those with dry or sensitive scalps, this may lead to irritation, itching, or flaking.
4. Dimethicone
Dimethicone is a silicone commonly used in hair care products to smooth the hair cuticle, reduce frizz, and improve shine. While it provides cosmetic benefits, it may also accumulate on the hair over time, particularly if not removed with appropriate cleansing. This buildup can leave some hair types—especially fine or naturally curly hair—feeling heavier, flatter, or more difficult to manage.
How to Spot a Good Shampoo
Now that we’ve discussed some ingredients you may want to avoid, let’s look how to spot a good shampoo and what to consider when selecting one for your scalp and hair.
Maintains a Slightly Acidic pH
A shampoo with a pH close to that of the scalp—typically around 5.5, with a range of 4.5 to 6.0—helps support the skin’s natural barrier and maintain a healthy scalp environment. Formulations within this range are generally less likely to disrupt the scalp’s pH balance, which is important for overall scalp health and normal hair growth.
Uses Natural Ingredients
Shampoos formulated with naturally derived ingredients can help cleanse the scalp while being gentler on the skin. Many botanical ingredients also provide moisturizing, soothing, and antioxidant properties that support overall scalp health. A well-formulated shampoo with naturally derived ingredients can be a good option for individuals with sensitive or easily irritated scalps.
Is Well Tolerated by Your Scalp
A shampoo should cleanse effectively without causing persistent discomfort. If you experience symptoms such as itching, excessive tightness, increased flaking, or scalp irritation after use, the formulation may not be suitable for your scalp. Because individual skin sensitivities and hair care needs vary, the most appropriate shampoo is one that is well tolerated and compatible with your scalp condition.
Tips for Washing Your Hair
To get the most benefit from your shampoo, consider the following practices:
Rinse with Lukewarm Water
Use lukewarm rather than hot water when washing your hair. Very hot water can strip the scalp of its natural oils, which may contribute to dryness and irritation. Lukewarm water provides effective cleansing while helping to maintain the scalp’s natural moisture balance.
Massage the Scalp Gently
Massage the shampoo gently into your scalp with your fingers closed together rather than spread apart to help distribute it evenly across the scalp. Gently massaging the scalp may also help remove excess sebum and product buildup. Use your fingertips throughout the process, and avoid scratching your scalp with your fingernails.
Allow the Shampoo Time to Work
After massaging the shampoo into your scalp, allow the lather to remain for approximately 2 to 5 minutes, or as directed by the product instructions. This provides sufficient contact time for the cleansing and active ingredients to work before rinsing thoroughly.
