It is completely normal to experience a mild tingling or warming sensation on the scalp shortly after applying Mirrolla Niacin Hair Lotion. This reaction is caused by the key active ingredient, niacin (also known as nicotinic acid or vitamin B3). In cosmetic applications, niacin is valued for its ability to encourage temporary flushing and support active microcirculation in the skin surface. This physiological response is often associated by users with the ingredient "working" to create a better environment for hair vitality.
While this sensation is generally harmless and indicates the product is engaging with the scalp, it is important to distinguish between mild warmth and irritation. If you experience strong redness, burning, or significant discomfort, this is a sign to stop use immediately. For those with very sensitive skin, it is advisable to introduce the product gradually to monitor how your skin responds. Always ensure you do a patch test before full application and avoid using the lotion on any areas of the scalp that are already irritated, damaged, or inflamed.
