What Is Clarifying Shampoo? Hair Care Experts Explain
While most haircare products are meant to cleanse your scalp and strands, not all shampoos were created equal. The difference-maker? Formulation, which determines how effective a product is and what its ingredients actually do to your hair. Clarifying shampoos, for example, use stronger surfactants (a.k.a. cleansing agents) than normal ones, making them extra robust for removing oil, build-up, and other debris. The built-in intensity of clarifying shampoos means you shouldn’t be using them all the time, however.
“A clarifying shampoo goes beyond the surface, delivering a deep cleanse to eradicate product build-up, residue, and hard water minerals,” says hairstylist Sharley Butcher. “Picture it as a revitalizing reset button for your hair.”
If you’re curious about how to incorporate a clarifying shampoo into your haircare routine, it’s important to understand its potential effects, both positive and negative. Frequency, too, is key. Ahead, three experts explain everything you need to know about the do’s and don’t’s of clarifying shampoo.
Who Will Benefit Most From a Clarifying Shampoo
Anyone with an oily scalp
The most obvious reason that shoppers reach for this product is the same reason dry shampoo is so popular: oily hair and scalp. “A clarifying shampoo may contain ingredients designed to lift away excess oil and residue, making them especially good for those with oily scalp,” says Dr. Garshick.
Anyone with limp, dull strands
If you feel like your curls are lifeless or your hair still feels weighed down after a wash, you may be dealing with a ton of product buildup. “Some of the signs that indicate you might need to use a clarifying shampoo are if you have dull, limp hair, heavy, greasy hair, a waxy or sticky feel to your hair, styling product build-up, or an itchy or flaky scalp,” says Dr. Callahan.
Anyone experiencing mineral or chlorine build-up
“Furthermore, if you live in an area with hard water, mineral deposits can accumulate on your hair, making it feel sticky and weighed down. [Or] if you swim regularly in chlorinated pools,” says Dr. Callahan. “Over time, these residues can accumulate on the hair, making it appear dull, greasy, and weighed down. Clarifying shampoos are designed to strip away these build-ups, leaving the hair clean, refreshed, and ready to absorb moisture and nutrients more effectively.”
Anyone who doesn’t shampoo frequently
If you’re able to stretch time between shampoos to a week or more, it’s helpful to use a clarifying shampoo. “Clarifying shampoos can be helpful for someone who doesn’t wash their hair frequently as it offers a deeper cleanse than a traditional shampoo,” says Dr. Garshick.
Anyone who feels like their hair just isn’t getting clean enough
Does your hair still feel dirty or oily after a shower? Butcher says that could mean it’s ready for a little clarification. “Listen to your hair; it might tell you it’s time for a clarifying session. If your hair doesn’t truly feel clean, it’s craving that deep cleanse.”
Downsides of Clarifying Shampoo
The most common downside of clarifying shampoo is that it can dry out the hair when used too often. “Clarifying shampoos, while effective at cleansing, can be drying to the hair if used excessively or if the hair is naturally dry or damaged,” says Dr. Callahan. “Because they have strong cleansing agents, they can strip away not only the excess oils and product residues but also some of the natural oils that keep the hair moisturized, leading to dryness, especially if the shampoo is used too frequently.”
Dr. Callahan adds that the deep cleanse also opens the cuticles of the hair, which “can make the hair more porous, allowing moisture to escape easily, and leading to dryness and frizz.” Additionally, this can lead to premature fading of hair color. “Those with color-treated hair should be cautious when using a clarifying shampoo,” says Dr. Garshick.
How Often to Use Clarifying Shampoo
“Even those with very oily scalps should limit use to one to two times per week while those with more dry or sensitive scalps should limit use to one to two times per month, if at all,” says Dr. Garshick. “That said, there are different clarifying shampoos designed for different hair and scalp types so it is best to find one specifically suited to your needs.” You can find our favorite expert-recommended clarifying shampoos here.
What to Do After Using a Clarifying Shampoo
“After using a clarifying shampoo, following up with the right steps is important to ensure your hair remains healthy, moisturized, and well-nourished,” says Dr. Callahan. “You should start by conditioning your hair with a moisturizing conditioner and apply a leave-in conditioner to provide extra hydration and protection. Make sure to avoid or limit the use of heat styling tools to prevent further dryness, as well as heavy styling products that can weigh down your hair, making it look greasy faster. If possible, allow your hair to air dry naturally or use cool settings with a hairdryer.”
