\"Using<\/a>
Using nicotinic acid to stimulate hair growth<\/figcaption><\/figure>\n

Question from Erika to the topic: In what cases are therapeutic shampoos used<\/a>. Question: \"More than once I have found in different sources advice on the use in home procedures of nicotinic acid to stimulate hair growth. Is it worth trying or is it just another legend on the net?<\/em>»<\/p>\n

Short answer:<\/strong>\u00a0It's not just a legend, nicotinic acid (niacin) actually has scientifically proven potential to stimulate hair growth.\u00a0But its use is risky and requires extreme caution.<\/em><\/strong><\/p>\n

Now for the details.<\/p>\n

How does it (supposedly) work?<\/h3>\n

Nicotinic acid is vitamin B3 (PP). The mechanism of its action on hair is as follows:<\/p>\n

    \n
  1. Strong vasodilator action:<\/strong>\u00a0This is the key effect. When applied to the skin, nicotinic acid causes a powerful blood flow to the treated area (hyperemia). This is accompanied by a characteristic redness, burning and tingling sensation.<\/li>\n
  2. Improved microcirculation:<\/strong>\u00a0Increased blood flow means a better supply of oxygen and nutrients to the hair follicles.<\/li>\n
  3. Stimulation of metabolism in follicles:<\/strong>\u00a0Improved nutrition can activate metabolism in follicle cells, potentially moving hair from the resting (telogen) phase to the growth (anagen) phase.<\/li>\n<\/ol>\n

    What does the science say?<\/h3>\n
      \n
    • There are studies showing positive effects.<\/strong>\u00a0For example, some clinical studies have demonstrated an increase in hair density and volume with nicotinic acid products in people with androgenetic alopecia (male and female pattern baldness).<\/li>\n
    • The effect is neither guaranteed nor universal.<\/strong>\u00a0Most studies are small and the response is highly individualized. What helped one person may not help another.<\/li>\n<\/ul>\n

      The main \"BUTs\" and risks of home application<\/h3>\n

      That's why blindly following advice from the web can be dangerous:<\/p>\n

      1. Severe adverse skin reactions:<\/strong><\/p>\n

        \n
      • Hyperemia:<\/strong>\u00a0Severe redness, burning, and itching are normal reactions, but they can be very intense and uncomfortable.<\/li>\n
      • Dryness and irritation:<\/strong>\u00a0Nicotinic acid can be very drying to the scalp, leading to flaking, tightness and even dermatitis.<\/li>\n
      • Allergic Reactions:<\/strong>\u00a0Rash, hives and more serious allergic manifestations may occur.<\/li>\n<\/ul>\n

        2. Unpredictable concentration.<\/strong>\u00a0Pharmacies sell solutions for injection (in ampoules) with different concentrations (usually 1%). Using this form for the skin is a lottery, as it is not intended for external use and may contain excipients that will cause irritation.<\/p>\n

        3. Deterioration of condition.<\/strong>\u00a0If used improperly (too often, high concentration), you can seriously damage the skin barrier, cause inflammation and aggravate hair loss.<\/p>\n

        4. Incompatibility with other procedures.<\/strong>\u00a0It should not be used together with other potent agents (e.g. minoxidil, acids) as the reaction can be unpredictable.<\/p>
