 Myths vs Facts about Coal Tar

Coal tar myths and facts

It can easily receive a bad rap on the internet, particularly now that the clean beauty wave is picking up steam. But the reality is that a lot of the fears associated with coal tar are based on misinformation.

  • Myth 1: Coal Tar is Always Dangerous

Reality: Cosmetic and therapeutic preparations of coal tar shampoo are highly refined and measured concentrations. The over-the-counter drugs are approved and safe when taken as directed. Concerns generally raised are those of industrial coal tar, not personal care products.

Reality: Modern research reveals no strong evidence supporting a cancer link with therapeutic coal tar shampoos Long-term clinical use has not demonstrated an increased incidence of cancer at cosmetic concentrations.

Famous for its ability to slow down the growth of excess skin cells, coal tar is most effective in combating visible flaking, itching, and irritation of the scalp.

Unlike before, coal tar shampoos are much safer and easier to use, and with the rising demand for anti-dandruff treatments, coal tar is a most effective and superior component of a flake-free and healthy scalp. 

 Calming Scalp Inflammation

Coal tar is very well known for its ability to soothe irritated scalps and reduce inflammation. This makes it an essential ingredient in medicated hair care products. Coal tar is known to prevent the quick turnover of skin cells on the scalp, which is usually known to cause irritations like redness and itching. Coal tar is an extremely effective treatment for irritated scalps related to dandruff, scalp psoriasis, and seborrheic dermatitis.

This helps them blend with the daily hair care routine with ease. Coal tar is an increasing part of the growing trend witnessed for focused scalp care.

Supporting Hair Growth Through Scalp Health 

Coal tar plays a significant role in the promotion of hair growth through the enhancement of the health of the scalp, an essential factor in the development of healthy-looking hair. The slowing down of the rapid accumulation of the skin cells prevents clogging in the follicles and flaking, an aspect that may hamper the process of hair growth in the body. It is frequently used in medicated shampoo solutions to counter scalp psoriasis, seborrhoeic dermatitis, and itching conditions, all agents that may debilitate the scalp by slowing down the health-giving processes within the body. With the use of coal tar shampoo, the body may experience the reduction of inflammation and the promotion of health within the scalp, an important factor that may enhance the proper delivery of oxygen and nutrients to the follicles responsible for the production of hair in the body.

Considerations and Precautions with Coal Tar 

It is pertinent to know the value and cautions related to the use of coal tar. Although coal tar is highly effective in the treatment of dandruff, Scalp Psoriasis, and Seborrheic dermatitis, one should always use it as advised. It has been observed that coal tar shampoos can make the scalp sensitive to the sun. Additionally, one might experience some irritation or drying effect, especially when using the coal tar products repetitively. It is advised to perform a patch test before using them fully and should not be applied on broken or irritated skins, except when advised by the dermatologist. Also, one should consult their healthcare provider in case one is pregnant or nursing a baby. When properly used, coal tar is safe and advised by dermatologists.

  1. Mild scalp irritation: Some may experience some temporary reddening, stinging, or discomfort, particularly on first use.

  2. Raised sun sensitivity: Coal tar also makes the scalp more susceptible to the sun’s rays and hence vulnerable to sunburn.

  3. Dryness or roughness: Over-use can cause dryness or brittleness if it is not conditioned properly on scalp or hair.

  4. Temporary hair or scalp discoloration: Light or gray hair can develop some discoloration, but this is often temporary.

  5. Folliculitis: In some rare instances, obstructed hair follicles may give rise to small papules or acne bumps on the scalp surface.

  6. Allergic reactions (very rare): Symptoms such as itching, swelling, and rash also warrant discontinuation of the drug.

To avoid these side effects, it is recommended to follow few Coal Tar Safety Guidelines: 

  1. Use coal tar shampoo strictly in accordance with the package or dermatological instructions.

  2. Avoid excessive sun exposure and apply sun protection to the treated area

  3. Do not apply on broken, irritated, or infectious skin unless used under the instructions of a physician.

  4. Before the first application, do a patch test for sensitivity

  5. Glow with a moisturizing conditioner to prevent dryness

  6. Consult a dermatologist before using during pregnancy and breastfeeding.

In conclusion, coal tar is still safe and effective in the treatment of dandruff, seborrheic dermatitis, and scalp psoriasis. By being informed about the side effects and taking the right steps with regard to safety measures, one can take full advantage of the medicinal properties possessed by coal tar for the proper healing of the scalp.

Frequently Asked Questions

Coal tar is a well-known treatment for dandruff, psoriasis, and other scalp conditions. It helps to reduce inflammation, flakiness, and itching by slowing down the overproduction of skin cells. Due to its antifungal and anti-inflammatory properties, coal tar is commonly included in shampoos for treating seborrheic dermatitis and scalp psoriasis.
While coal tar is effective for treating scalp conditions like dandruff and psoriasis, its impact on hair growth is indirect. By reducing scalp irritation, flakiness, and inflammation, coal tar helps create a healthier environment for hair follicles to thrive. This may contribute to improved hair density and reduced hair shedding, but it's not a direct solution for hair loss.
When used correctly, coal tar shampoos are generally safe for the hair and scalp. However, overuse or improper application can lead to dryness, scalp irritation, or increased hair breakage. It’s important to follow product instructions and apply coal tar-based shampoos only as needed to avoid potential negative effects on your hair texture or overall scalp health.
For effective dandruff treatment, it is recommended to use coal tar shampoo 2-3 times a week. Overuse can lead to excessive dryness of the scalp. To maintain optimal scalp health, consider alternating with a moisturizing or mild shampoo. Regular use can help control scalp psoriasis and seborrheic dermatitis, while reducing flakes and irritation over time.
While coal tar shampoos are beneficial for many, some individuals may experience mild scalp irritation, dryness, or itchiness. In rare cases, prolonged use may lead to sensitivity to sunlight. It's important to do a patch test before using any coal tar-based product to ensure there are no adverse reactions. Always consult a dermatologist if you have concerns.
Coal tar is generally safe for adults, but it may not be suitable for those with sensitive skin or children under the age of 12. For individuals with sensitive scalp or skin conditions, alternative treatments like tea tree oil or salicylic acid-based shampoos may be more appropriate. Always consult a healthcare provider before using coal tar-based products on children.
Coal tar and tea tree oil both address dandruff and scalp issues, but they work differently. Coal tar is more effective for severe conditions like psoriasis and seborrheic dermatitis, as it reduces inflammation and slows skin cell turnover. On the other hand, tea tree oil is a natural antifungal and can be gentler on the scalp, ideal for more mild dandruff and general scalp care.
