Frequently Asked Questions (FAQs)
1. How long does it take hair to transition to shampoo bars?
When you start using natural products your hair readjusts by over producing sebum. Some people don't experience a transition period at all but it can last between 2-3 weeks or even longer for some. If you live in a hard water area the transition period is usually longer, a water softener helps hugely.
2. Can you use soap bar on hair?
These days, bar soaps are not recommended for washing your hair. If you were to use bar soap instead of shampoo, it would leave a soap scum behind. And if you have hard water, it'd be very hard to rinse it off of your hair and your scalp. As far as shower gel goes, it's also not recommended for your hair.
3. How long do hair bars last?
Each mighty bar gives you 80-100 washes (depending on hair shape, thickness and length) and is a lot lighter and slimmer than a shampoo bottle.
4. Do shampoo bars make hair dry?
Sulphates contain cleansing properties that lather, but they can also irritate the ph balance in your scalp and cause hair to become dry and brittle. Sulphate free haircare products such as some premium shampoo bars have an ultra mild, ph balanced formula that's gentle on your hair and scalp.
