Laser hair removal is a popular method for permanently removing unwanted hair. At Laser ONE, our primary goal is to achieve optimal treatment results and ensure the safety of our customers. Honesty and communication with our customers play a decisive role in this. While many people take dietary supplements, very high doses of certain supplements can sometimes affect the success of laser treatment.

In this article, we would like to take a comprehensive look at the four most common laser hair removal supplements and their potential effects on treatment. It is important to emphasize at this point that each person is individual and the effects are not the same for everyone. Therefore, individual differences should always be taken into account. So, let’s go! 😊

1. vitamin D

What is vitamin D?

Vitamin D is a fat-soluble vitamin that is essential for bone and tooth health. It supports the absorption of calcium and phosphate from food and is often referred to as the“sun vitamin” as it is synthesized by sunlight on the skin. In the winter months or when there is insufficient sunlight, many people turn to vitamin D in the form of tablets or drops. A normal dosage of vitamin D is usually around 800 to 1,000 IU (International Units) per day.

Influence on the laser treatment:

If vitamin D is taken in very high doses (more than 5,000 IU daily) and on a regular basis, it could potentially stimulate hair growth. Our experience has shown that this can affect the outcome of laser therapy. Increased hair growth means that more sessions may be required to achieve the desired result. However, it is important to emphasize that these effects can vary from individual to individual and may not occur in everyone. Therefore, people who take vitamin D in very high doses over a prolonged period of time may need to adjust or reduce their dosage.

2. multivitamins

What are multivitamins?

Multivitamins are dietary supplements that contain a variety of vitamins and minerals to support daily nutrient intake. They are often taken to fill gaps in the diet and promote overall health.

Influence on the laser treatment:

As with vitamin D, high-dose multivitamins, especially those with a high vitamin D content, could also stimulate hair growth. However, it is important to emphasize that multivitamin supplements usually do not contain as high amounts of vitamin D as pure vitamin D supplements. Therefore, the potential effects on treatment when taking multivitamins are usually less pronounced. Nevertheless, people who regularly take very high doses of multivitamins should be aware of the possible effects and possibly adjust their intake during laser therapy.

3. proteins

What are proteins?

Proteins are essential macronutrients that are vital for the formation and repair of tissue, the production of enzymes and hormones and for a variety of other bodily functions. They are an important part of our diet and are often taken in the form of food supplements, especially by athletes and bodybuilders. These include protein shakes, clear whey and protein bars, which offer a convenient way to increase your protein intake.

Influence on the laser treatment:

It is important to emphasize that only very high protein intakes, such as those commonly consumed by bodybuilders, could potentially affect the outcome of laser treatment. A normal protein intake, which is in the range of about 50 to 70 grams per day for most adults, is not a problem and has no negative impact on the treatment.

Very high protein intakes, defined as more than 2 grams of protein per kilogram of body weight daily over an extended period of time (several weeks to months), could theoretically stimulate hair follicle growth and thus increase the number of laser sessions required. It is recommended that you inform us in such cases, as these effects vary individually and may not occur in everyone.

4. St. John’s wort

What is St. John’s wort?

St. John’s wort (Hypericum perforatum) is a medicinal plant that is often used to treat mild to moderate depression and anxiety. It is known for its mood-enhancing and calming properties. The plant contains bioactive compounds such as hypericin and hyperforin, which help to improve mood and relieve stress.

In addition to its use for psychological complaints, St. John’s wort is also valued for its anti-inflammatory and antimicrobial properties. It can be used in the form of teas, tablets, capsules, tinctures and oils. However, St. John’s wort can interact with various medications, so it should always be discussed with a doctor before taking it.

Influence on the laser treatment:

St. John’s wort is an absolute contraindication for laser treatment, as it can have a light-sensitizing effect! ⛔ This means that the skin reacts more sensitively to light, which increases the risk of side effects such as burns and hyperpigmentation. People taking St. John’s wort should therefore refrain from laser treatment.

📌 Conclusion:

Taking certain dietary supplements can affect the effectiveness and safety of laser hair removal. It is important to emphasize that only very high intakes of vitamin D, multivitamins and proteins could stimulate hair growth and thus require more treatments. However, these effects may not occur in everyone, as each person and body reacts differently. Normal dosages of these supplements do not usually pose a problem.

St. John’s wort is an absolute contraindication due to its light-sensitizing effect and should be avoided during laser treatment. At Laser ONE, it is important to us that our customers communicate honestly with us and inform us about their intake of dietary supplements. This enables us to achieve the best results and guarantee safety.
