The cost of the bars from Amazon is $23.48 with the promise of up to 75 uses, with one bar being the equivalent of 3 (plastic) bottles. What size bottle is wholly unknown, but okay, let’s assume 13 to 16 ounce bottle. Much of this depends on how much hair you have.
As a comparison to a similar company that sells liquid shampoo and conditioner, a 13.5 ounce bottle of Love, Beauty and Planet shampoo costs $8.99 at Target, so three bottles would be $26.97 and another 3 bottles of conditioner would cost the same bringing the total to $53,94. So yes, a big savings buying the bars.
At the Leafinty site, the same set costs $32,99, so not sure why the difference in price from Amazon.
Leafinty also offer bars for nine different types of hair or scalp treatments like sensitive scalps, anti-hair loss, deep cleaning or troubled or sensitive scalps.
