Transform your scalp care routine with Bea’s Bayou’s YeastDefense™️ Moisturizing Shampoo, specially formulated to support itchy, flaky, and sensitive scalps, including those prone to dandruff, Seborrheic Dermatitis (SebDerm), and scalp eczema. This deeply hydrating cleanser gently purifies without stripping, while delivering lasting moisture and scalp-soothing botanicals that help restore balance where it matters most—your scalp’s microbiome.

Infused with a therapeutic blend of probiotic extracts, peppermint, tea tree, rosemary, and white willow bark, this refreshing shampoo targets the root causes of persistent itch and flakes by calming inflammation, balancing oil production, and exfoliating buildup. Meanwhile, argan oil, black pepper, and rice protein help strengthen hair strands and improve elasticity and shine.

Perfect for dry, textured, color-treated, curly, or itchy scalps, this shampoo gently cleanses while rehydrating and restoring comfort to sensitive skin. Unlike harsh anti-dandruff shampoos, it’s free of sulfates, parabens, silicones, and synthetic fragrances—making it safe for daily or weekly use.

Finally Relief !

Just finished washing my hair today with the Good Biome Clarifying Shampoo. What can I say. My scalp feels so soothed and clean but not stripped. I have tried every dandruff and SD over the counter shampoo you can think of. Sulfur, zinc, selenium sulfide, coal tar, ketoconazole you name it. They gave temporary relief but in 3-4 days my flakes and itchy scalp would be back. Not to mention my hair and scalp would smell rank a few days after washing. Must be the fungus overgrowth to blame. This probiotic solution really is a game changer. Most of the ingredients I have come across before except the probiotics. I also used the scalp oil and my scalp doesnt feel coated or heavy. Didnt pick up the conditioner or scalp solution because I am allergic to marula and black walnut but the shampoo seems to be treating this condition for me. I eat a balanced diet and try to stay away from sugars. Taking a tablespoon of cold pressed hemp seed oil everyday also keeps my scalp clear all week.

Cleanse your your hair and scalp really good!

Seems to help

I’ve only used the shampoo twice, but it seemed to Help with my dermatitis. If it works like the scalp solution which is awesome I’ll be very happy.

New staple

This is my second bottle of this shampoo. I’m very particular about what products I use on my hair and scalp. This shampoo does a great job at cleansing my scalp and locs. It’s light and doesn’t leave buildup or that dry/stripped feeling. I have oily, flaky scalp. Paired with the scalp solution, I get more “good” scalp days, less itching and minimal flakes.

Good Biome Shampoo

Once again Bee's Bayou has given me outstanding service as well as outstanding products. There was a problem with the delivery of my order. The packaging was severely damaged and Bea's not only replaced it with no charge, they upped the packaging by putting their usual packaging (which is usually great) at my request they also put it in a box. And that one arrived in perfect condition.

What is the Microbiome?

The skin microbiome is a natural ecosystem of microorganisms that protects the skin, supports the immune system, and maintains balance. When disrupted by harsh products or environmental factors, it can lead to issues like inflammation, redness, and an itchy scalp, often linked to conditions such as seborrheic dermatitis or eczema.

Probiotics, known for their ability to restore balance to the microbiome, have been shown to reduce irritation and improve the appearance of conditions like itchy scalp and eczema. By calming inflammation and supporting the skin’s natural defenses, probiotic-infused skincare offers a gentle, science-backed approach to promoting healthier, more comfortable skin.

Since 2020, Bea's Bayou® has offered hair and skin solutions for diverse people, packed with herbs and probiotic extracts to bring quick help!

7 Types of Eczema

Eczema is a group of skin conditions that includes seven main types, though research continues: atopic dermatitis, contact dermatitis, dyshidrotic eczema, nummular eczema, seborrheic dermatitis, stasis dermatitis, and neurodermatitis.

Scalp eczema, often linked to Seborrheic dermatitis, is one of the most common forms, causing itchy, flaky, and inflamed skin on the scalp. This condition can be frustrating and challenging to manage, but Bea’s Bayou Skincare offers a natural, effective options, formulated with prebiotic ingredients and herbal extracts to soothe fast!

Our Origin Story

Welcome to Bea’s Bayou Skincare! I’m Arielle, the proud founder and creator of this special brand. Bea’s Bayou is named after my Louisiana-born grandmother, Beatrice, and the bayou near her home where I spent countless joyful days as a child. My grandmother was a true nurturer—raising animals, growing fruits and vegetables, baking the best pies in the area, and turning to herbs as natural healers. Her wisdom inspired my mother and now guides me in creating products that honor our heritage.

Living with Seborrheic dermatitis, I know the struggle of feeling insecure about my scalp. Probiotics changed my life internally, and research showed me they could work wonders topically too. Combining microbiome-friendly ingredients with bayou-inspired herbs, I created Bea’s Bayou to help others find relief, joy, and confidence in their skin. What began as a DIY solution to soothe my scalp has grown into a trusted collection of lightweight, herbal, and fast-acting products—thanks to incredible customers like you.

I hope Bea’s Bayou brings you the comfort and confidence you deserve, naturally and effortlessly! 🌿 - Founder, Arielle Brown
