7. Frequently Asked Questions
Does Fusio-Scrub replace shampoo?
Yes. As part of the professional ritual, Fusio-Scrub replaces traditional shampoo thanks to the combined action of scrubbing, water, and massage.
Why doesn't the scrub lather immediately?
The texture is intentionally thick. Lather appears when water is gradually added during the massage, usually in three or four steps.
Can the treatment make hair oily or heavy?
Correct dosage should not weigh down the hair. However, an excess of essential oil can make roots heavy or oily the next day.
Can essential oil be applied directly to the scalp?
No. The oils are highly concentrated and must always be diluted in 20 ml of Scrub before any contact with the skin or scalp.
Which combination should be preferred for thinning hair?
Energizing Scrub combined with Ginger Stimulating Oil is generally recommended to purify the scalp and stimulate microcirculation.
Is the treatment suitable for men?
Yes. The protocol is suitable for both men and women and can address needs for purification, freshness, volume, or relaxation.
