Review: The Bar's Ability to Lather - It's too soon to tell if this shampoo bar's biotin (etal) content improves hair health, but it isn't too soon to tell if this shampoo bar is like so many others I've tried. Past shampoo bar use for me has been equivalent to rubbing a brick on my head and in my hands to get later. No so with Arencia! It lathers easily and with lots of volume. I'm so much closer now to really being able to discontinue the use of plastic bottles. Thanks Arencia.
Review: Buy this for sure. - Definitely recommend this product if your hair is falling or you dealing with postpartum get this and enjoy your fuller Hair.

## Features

- ARTISANAL QUALITY, HIGH SUSTAINABILITY : We strive to help build a sustainable world and we believe that this comes from taking small but meaningful changes. Good intentions are important but good quality is also essential. We offer our customers sustainable products made with artisanal formulas that change the paradigm of beauty by providing better quality alternatives to traditional products that come in plastic bottles. Beauty does not have to come in plastic.
- 100% VEGAN, NATURAL INGREDIENTS : We believe in harmony and coexistence with nature. All of our products are made with natural, vegan, cruelty-free, organic, plant-based, ethically sourced, and eco-friendly ingredients.
- 0% HARMFUL INGREDIENTS : We also left out all the unnecessary ingredients that are proven to be or are potentially harmful. All of our products are silicone free, paraben free, sulfate free, petrolatum free, and formaldehyde free.
- ZERO WASTE PACKAGING : We believe in sustainable beauty. Sustainability isn't just limited to the ingredients we use - it's just the start. Sustainability means that the entire process from making to packing is all up to the highest standards. Our products are packaged in FSC certified paper boxes which are made of 100% recycled paper. They are not being coated in plastic, making them 100% compostable. We believe that 'rawness' is beautiful in itself.
- LONG LASTING : Do not underestimate the shampoo/conditioner/cleansig bar for its size. Equivalent to 5 bottles of bottled shampoos, one shampoo/conditioner/cleansig bar can last up to 3 months. Considering this, these shampoo bars/rinse bar are/is a much more economic alternative to liquid shampoos.

### ⭐⭐⭐⭐ Tames frizz!!
*by K***K on April 17, 2024*

I have super frizzy and dry hair. Tried many many different kinds of hair products from shampoo, conditioner, leave-in moisturizer, oil etc... and nothing seems to work. This tames the embarrassing frizz right from the first application! So happy for that! However, may take time to see the effectiveness for dryness (especially ends/split ends) and the shine to hair. I'm not a fan of bar soap, therefore, there's an adopting factor and adjustment. It doesn't lather up or feel the smoothness like regular soap, so may wonder if the product actually applied on hair when used. Hence, it took many rubbings to convince myself that the product got on my hair. Seems like it applied better in running water even though I wonder if product would also wash thin during the process. It doesn't feel silky and smooth like other conditioners, but does work in calming the frizz. So, if nothing else, love it for minimizing frizz!
