Frequently Asked Questions

How do I use the shampoo and conditioner bars?

Wet your hair and the bar, then glide the shampoo bar directly onto your scalp. Massage into a rich lather and rinse. For conditioner, glide the bar along the lengths of your hair, let it sit for a few seconds, then rinse thoroughly.

When will I start seeing results?

Most people notice improvements quickly, but results build over time. Here's a general timeline:

After the first few washes: Hair feels cleaner, lighter, and free of buildup. Many also notice improved softness and scalp comfort.

Within 2–3 weeks: Increased shine, smoother texture, and better overall manageability as your hair adjusts to the cleaner, more nourishing formulas.

By 4–6 weeks: Reduced breakage, less shedding, and stronger, healthier-feeling strands.

By 8–12 weeks: Full results — hair looks visibly healthier, fuller, and more resilient with consistent use.

Everyone's hair is different, but most customers report meaningful changes within the first month.

How long do the bars last?

Our last Lasts 50-75 washes so they can replace 2-3 bottles + last up to 6 months.

Our most popular subscription frequency is 3 months and is ideal for those who wash their hair 2-3x per week.

Your bar longevity will be impacted by usage, storage and hair length and thickness. Extend the life of your conditioner bar with our Wooden Soap Dish, our Silicone Soap Dish, or our Sisal Soap Saver bag.

Isn’t $15.99 a lot for one bar?

If you break it down, not at all! Our bars replace 2-3 bottles of liquid shampoo and conditioner, so you can compare the price to a $5 bottle of shampoo. Even better? Our bars don’t contain water, so our ingredients aren’t diluted like regular shampoo and conditioner. You get super concentrated, super nourishing ingredients for up to 75 washes with a single bar!

Can I use your shampoo and conditioner bars on curly/color-treated/dry/gray or silver hair?

Yes, across the board! Here's why:

We never use sulfates or silicones, so our bars are Curly Girl Method-safe

Our customers with silver hair report no issues with brassiness or yellowing

Our ingredients, such as cocoa butter and coconut oil, deeply moisturize your hair: making our bars perfect for color-treated and dry hair

Will the shampoo bar make my hair feel waxy or heavy?

No — our bars are formulated without silicones or residue-causing fillers. Most customers report their hair feels lighter, softer, and cleaner after switching.

Is there an adjustment period when switching from liquid products?

Some people experience a short transition as their scalp adjusts to cleaner, non-toxic ingredients. This usually resolves within 1–2 washes, and hair quickly becomes softer and more balanced.

Are the bars good for sensitive scalps?

Yes. Our formulas are gentle, dermatologist-approved, and free from sulfates, parabens, and synthetic fragrances, making them great for sensitive scalps.

Do the bars work for all hair types?

Absolutely. Whether your hair is fine, thick, curly, coily, or straight, our bars are designed to cleanse and hydrate without weighing hair down.

Are they environmentally friendly?

Yes — each bar is plastic-free, low-waste, and highly concentrated, reducing the need for single-use bottles.

How should I store my bars to make them last longer?

Keep them dry between uses. Place them on our soap dish or shower caddy to prevent premature melting.

Can I travel with them?

Definitely. They’re TSA-friendly, compact, and spill-proof — perfect for travel, gym bags, or on-the-go use.
