In a hypothetical experiment, do you think that having a patient soak their scalp in a solution suspected to have hair growth promoting effects would be more beneficial than simply applying the solution topically with a dropper or fingertips? Especially if the solution contained herbal or natural ingredients that would not cause harm if introduced into the bloodstream. Say for 10 minutes soaking time and submerging the head in a bowl shapped apparatus or container filled with the solution.
Please explain why or why not. Thank you.
hello
although it seems possible, but how simple or practical it is
Ayurveda describes this methodology as Shirovasti, where a leather cap is put over head and oil is slowly poured in. The procedure is continued for approx 45 minutes and yields extreme therapeutic benefits in stress, anxiety, eye, ear, scalp and hair related problems. It is indeed very much practical but as far as your query goes whether it is better than head massage or topical application, it can be deduced only with comparative analysis. Would try searching for and posting such links, if available.
This follows simple pharmakokinetic rules: The effect increases (to a certain level) with the amount of active reaching the target (hair root cells). The amount depends on the penetration, which is dependent on the concentration gradient as the driving force, the amount of applied active (reservoir size) and TIME.
All these facters should be increased when soaking. Moreover, humidity is high over a longer period of time, which should strongly influence skin Penetration rate.
