This shampoo bar transformed my fine, menopausal hair. Instant fullness, no scalp showing, and no need for extra thickening products. I’ve tried dozens of bottled and solid shampoos over the years, but this is the only one that really works. I’m subscribing because nothing else compares!

Hilary H.

If your hair is fine, flat, prone to breakage, or affected by hormonal or stress-related changes, this bar was made with you in mind. It addresses the key factors behind thinning and lack of volume.

Suitable for every hair type, texture, and age. Even customers who were sceptical report they noticed fuller-looking hair and a healthier feel after just a few weeks.

      Frequently Asked Questions

      Yes - when they’re formulated properly, shampoo bars work just as well as liquid shampoos.

      Ailynné shampoo bars are NOT soap. They’re made with the same high-performance cleansing and conditioning ingredients you’d expect from a premium liquid shampoo, just without the added chemicals and water. The result is a rich lather, effective cleansing, and hair that feels clean, soft, and healthy - never stripped.

      Yes, but don’t just take our word for it! Check out the thousands of 5 star reviews from people of all ages using our shampoo and conditioner bars.

      Absolutely! Rub the bar directly on wet hair or between hands - it creates a rich, creamy lather. For extra foam, pair it with our silicone scalp massager.

      No! Our bars are free from sulphates, parabens, silicones, phthalates, and synthetic fragrances. Instead, we use natural, EU-sourced ingredients like calendula, castor oil, and aloe vera to cleanse and nourish hair gently with emphasis on supporting a healthy scalp microbiome for long-term results.

      1 bar = 60+ washes. It outlasts around 2 liquid shampoo bottles, saving you money and plastic from landfills.

      Depending on your hair type and how frequently you wash your hair, some people see results immediately and some people may start to see results in a few weeks.

      Yes! Our shampoos are free of sulphates, silicones and parabens which means they’re gentle enough to be used on colour treated hair without stripping colour.

      We recommend a subscription, so you can enjoy savings and get your products delivered right to your door. This way, you’ll never run out! You can skip, amend or cancel any time!

      A little goes a long way! Everyone’s hair is different, so expect a bit of trial and error until you find out what works best for you. Start with enough to clean from your roots and scalp to the ends of your hair. If you’re not seeing results, we recommend applying more during your wash time.

      100%! We never test on animals and all ingredients are vegan and ethically sourced.
