Growing up, my sister and I shared a bathroom. She loves toiletries and beauty products, so our cabinets looked like the health and beauty section of a supermarket. She had straightening shampoo for curly hair, deep conditioners for dyed hair, and frizz control serum for humid days, in addition to creams, lotions, powders, and boxes of makeup.
When I went to college, and eventually found an apartment for rent, I realized that I had to find ways to save money on beauty products and maximize space in my tiny bathroom. I found that I could get the most value by using multi-purpose products.
