The Shampoo That People With Itchy, Sensitive Scalps Swear by Is on Sale for as Little as $10

For those with greasy hair, there might be no better relief than finally hopping into the shower and washing your hair with a refreshing shampoo. Even if your strands feel cleaner than ever, it's important to take care of your scalp to soothe away itching, too. The scalp and roots of your hair are the ultimate starting point for ensuring healthy hair, and therefore are worth just as much TLC.

Yet taking care of both your scalp and your individual strands doesn't necessarily mean you need to have a bunch of different bottles, tubs, and jars taking over your shower shelf. Reviewers say Rene Furterer's Astera Fresh Soothing Freshness Shampoo is the calming double-duty shampoo that you'll love if you have an unbearably itchy scalp. It's "perfection" for people with irritated, uncomfortable scalps, according to shoppers—and it's 20 percent off with code EARTH2022 thanks to the brand's sitewide Earth Day 2022 discounts.

To buy: From $10 with code EARTH2022 (was $12); renefurtererusa.com.

The French haircare brand has been a favorite with shoppers who want to improve hair health as well as get glossy, shiny, voluminous hair, and the Astera Fresh line that the soothing shampoo is from is no different. It's formulated with echinacea angustifolia root extract (also known as purple coneflower), which is part of the Asteraceae family whose plants have anti-inflammatory, antimicrobial, and antioxidant properties.

In addition, the shampoo is made with eucalyptus and peppermint essential oils, so massaging it into your hair and scalp can easily double as a quick aromatherapy session. Both ingredients work to refresh and add a cooling sensation to the scalp, which reviewers say helped significantly stop itching during the day. "This feels so nice on my irritated scalp and I noticed a difference after one wash," wrote a shopper. "If you have irritation, itchiness, or redness on your scalp, try this shampoo."

If you want to take your scalp treatment to the next level, Rene Furterer also offers a scalp serum and a pre-shampoo concentrate from the same line that helps reduce inflammation. The concentrate comes in a bundle with the shampoo, too, and it's also on sale as part of the brand's Earth Day promotion.

To buy: $66 with code EARTH2022 (was $82); renefurtererusa.com.

With summer and humid days just around the corner, your scalp can easily buildup debris and grease, so now's the time to shop Rene Furterer's Astera Fresh line. Grab the shampoo for as little as $10 with code EARTH2022 before Rene Furterer's sitewide sale ends on Monday, April 25.
