Some people may feel anxious if their hair loss increases despite taking medication. This article explains the reasons and duration of initial hair shedding caused by minoxidil. It also discusses the causes of prolonged initial hair shedding. Please use this information as a reference. What is initial hair shedding from minoxidil? Initial shedding refers to temporary hair loss that occurs shortly after starting to use minoxidil. The timing of when hair loss begins varies from person to person, but it is a symptom that often appears around the time treatment starts. Initial hair shedding is related to the hair cycle. The hair cycle is the cycle in which hair grows, falls out when it becomes old, and then grows again. This hair cycle is divided into three phases: the growth phase, the regression phase, and the resting phase, and has the following characteristics. Growth phase: This is the stage in which hair grows, during which the division of hair matrix cells is active. Regression phase: In the process of transitioning to the resting phase, hair that has reached the end of its life cycle falls out over a period of 2-3 weeks. Resting phase: Hair growth completely stops, and old hair falls out. The hair cycle progresses through the growth phase, regression phase, and resting phase in sequence, before returning to the growth phase, and the cycle repeats. When you start using minoxidil, the resting phase of this cycle is shortened, and the hair transitions to the growth phase more quickly. The phenomenon of hair falling out as the hair cycle attempts to return to normal, after it has entered the resting phase and stopped growing, is called "initial shedding." The period during which initial hair shedding occurs with minoxidil. Initial hair shedding with minoxidil typically begins about 10 days to 2 weeks after starting use and usually ends within 1 to 2 months, although this varies from person to person. In some cases, it can last up to 3 months, and the amount of hair loss also differs from person to person. Some people are shocked by the phenomenon of hair loss and stop treatment, but initial hair shedding is a necessary process for regulating the hair cycle and promoting hair growth. It's important to continue treatment for about three months rather than stopping immediately. Even if initial hair shedding occurs, continuing treatment will allow the hair cycle to normalize, and the hair growth effects of minoxidil will become apparent. Reasons why initial hair shedding from minoxidil may persist. Initial hair shedding can occur as part of the process of restoring the hair cycle to normal, but if it doesn't subside after about three months, other causes may be considered, as listed below. Other diseases besides AGA Disruption of lifestyle The following sections will explain each of the causes in detail. Other diseases besides AGA If initial hair shedding lasts for more than three months, it may be caused by a condition other than male pattern baldness (AGA). Possible conditions include the following: Alopecia areata traction alopecia Seborrheic alopecia Since these types of alopecia require different treatments, if you suspect any of the above conditions, please visit a medical institution promptly and seek a doctor's diagnosis. When you do, it would be helpful to show the doctor any medications you have been using or their instructions. In addition to the diseases mentioned above, scalp damage and deterioration of the scalp environment may also be contributing factors. Minoxidil, which is applied directly to the scalp, can cause side effects such as itching and redness of the scalp. The scalp is a difficult area to check yourself, but scalp inflammation can also cause hair loss, so if you notice any discomfort, consult a medical professional. Disruption of lifestyle Irregular lifestyle habits may be hindering the regulation of your hair cycle. Review your lifestyle to see if you have any of the following irregular habits. Extremely short sleep duration Poorly balanced diet stress Excessive drinking and smoking Lack of sleep not only prevents the secretion of growth hormones essential for hair growth, but also negatively impacts the body. In terms of diet, nutrients such as protein, minerals, and vitamins are crucial for hair growth. Review your eating habits and consciously incorporate these nutrients into your diet. Poor sleep quality, poor diet, and other lifestyle irregularities may reduce the effectiveness of minoxidil. If you have any concerns, consult a medical professional. summary Initial hair shedding with minoxidil is a phenomenon where hair falls out around 10 days after starting treatment. It may be worrying to experience hair loss when you first start treatment, but this is a normal process that occurs as your hair cycle normalizes. It's important to continue treatment rather than stopping it immediately. Initial hair shedding usually ends in about 1-2 months, but it can last up to 3 months for some people, so there are individual differences. If hair loss persists for more than three months, it could be due to an unhealthy lifestyle or another underlying medical condition. If you are concerned, please consult a medical professional for a diagnosis. You should also consult a medical professional if you experience any other abnormalities besides hair loss.
