Lightweight Hairdressing: How much to use?

Yes! There is enough product on my finger to oil your entire scalp and then some. Just emulsify or spread this amount throughout your hands first. Then massage into the scalp and hairline without reaching for anymore product.
Design Essentials has their Herbal Complex that is lightweight enough to apply to the scalp without weighing the hair down. The best thing is that this jar is only around $9 retail price.

In summary, "less is best" when dealing with oils and hairdressings. It is better to add more as needed than to oversaturate too soon.
