Just the Facts: Is It Time for You to Switch Shampoos?

Growing up, we often heard heated debates among friends, family, and beauty gurus about the formulaic need to switch shampoos every once in a while. Word was that if you didn’t regularly switch out your favorite formulas, your hair would eventually lose its luster and shine. Many so-called experts preached that strands simply “get used to shampoo,” but others had their doubts. We all know how fickle and callous Mother Nature can be, but would she really punish us for loyalty to our beloved products? And if so, how will we know when it’s time to make the switch? We asked our team of haircare professionals to put these questions to rest, once and for all.

Busting the myth

First things first, we’d like to put an end to the misconception that shampoo becomes ineffective from hair accumulating a "tolerance" to the formula. That’s an old wives' tale—probably invented by some '50s advertising agency in an effort to sell new shampoo—however, you should still be sure to regularly switch out your bottles for a variety of other factors.


Professional haircare products are specially formulated to address specific hair challenges, not unlike prescriptive medication. The type of shampoo and duration of use depends on the issue in need of a remedy. Seasonal, environmental, dietary, chemical, and processing changes are all reasons to switch up your shampoo-conditioning routine to provide the right balance of moisture, nutrition, and composition for optimal hair health.

The seasonal switch

Hair is very vulnerable to the elements, and because of this, requires extra care. Arid winter air dehydrates your hair, requiring a shampoo with extra moisture and protection in the colder months. The same shampoo, however, may leave hair feeling heavy, unwashed, and greasy in the humid, summer air. Active summer hair feels gritty and damaged from chlorine, salt, and lake life, so a clarifying shampoo, like DESIGNLINE Clarify Shampoo, would work well to strip summer buildup and restore your hair’s natural luster.


However, prolonged use as a go-to shampoo may eventually work against your strands, requiring you to balance your routine with a moisturizing shampoo like Paul Mitchell Awauphi Shampoo to hydrate and soften your strands. As the hair absorbs the formula’s beneficial moisture, its texture, appearance, and manageability will gradually improve. Then, when no longer showing the ravages of summer, the hair—now in better condition—will need to be maintained with a different shampoo.

When you dye it

The golden rules for color-treated hair? Shampoo your strands sparingly, never wash with warm water, and view your shampoo as a "pigment insurance policy"—you get what you pay for. Fresh, new color requires fresh, professional products. Don’t leave the salon without asking your stylist for detailed instructions in at-home care. This is especially important if your stylist bleached your 'do from dark to blonde, or added a heavily pigmented color like vibrant red. Your stylist should send you home with specific directions and product recommendations to help your color last.


Just as seasons and hair colors change, so should your shampoo. Expect an improvement in your hair with every switch, and if you don’t see results—or when they begin to cease showing—it’s time to consider a different product in your routine. The best results come from sage advice from a seasoned professional. Visit your Signature Style stylist to find the formula that works best for you. They’ll be happy to help you look and feel your best.
