1What's the difference between Giovanni's oil serums and lightweight serums?
Oil serums are richer and better for dry, thick, or curly hair that needs deep moisture and frizz control. Lightweight serums work better for fine or thin hair as they won't weigh strands down while still providing shine and heat protection.
2How do I know if a Giovanni serum is right for my hair type?
Check the product description for your hair concern—Giovanni makes serums specifically for frizz control, shine, damage repair, and volumizing. If you have dry or damaged hair, look for serums with argan oil or marula oil; for oily scalps, choose lightweight silicone-free options.
3What size bottle should I buy for regular use?
A 50ml bottle typically lasts 2-3 months with regular use since serums are concentrated and you only need a small amount per application. If you use serum daily on long hair, a 100ml bottle offers better value and longer between purchases.
4Are Giovanni serums worth buying over cheaper alternatives?
Giovanni serums are mid-range priced and known for quality ingredients without silicones in most products, making them better for long-term hair health than ultra-cheap options. They're worth it if you have damaged or frizzy hair that needs consistent care.
5Can I use Giovanni serum on wet or dry hair?
Most Giovanni serums work best on damp hair after towel drying, as this helps them distribute evenly and seal moisture in. Applying to completely dry hair can make hair look greasy, so use less product and focus on the mid-lengths and ends.
