4. Reapply the lotion to the scalp daily or at least 3 times a week
You should see an improvement in scaling (dry skin) on the scalp any time from the first use to within 2 weeks of applying at least 3 times per week.
The Science of the DIY 10% Glycerin Scalp Leave On Lotion
The study in Thailand was based on 274 people both male and female. The scientists chose not to go down the antifungal route that is commonly used to treat dandruff (i.e the commercial dandruff shampoos). Instead they chose to tackle the loss of scalp hydration that is seen with dandruff with a humectant (a product that draws water to itself).
You may therefore wonder if this is a permanent solution since they are treating the symptoms rather than the cause. This is a valid concern and to address this, the paper did say that after 8 weeks of following the regime, the study subjects were asked to stop and the dandruff flaking did not return in the following week (with no lotion used in that week).
For clarity, please note that the recipe above is not the exact one used in the study, there were other ingredients in the product including fatty acids and sunflower oil which were proposed as additional moisturising ingredients.
