Common questions about DHS Tar Shampoo (FAQ)
Q: Will DHS Tar Shampoo affect colored or treated hair?
Official labeling indicates that discoloration of hair is a rare possible effect associated with the product. Specifically, official safety information mentions this possibility for gray, blonde, tinted, or bleached hair. If an individual has chemically treated hair, they can be aware of this possibility, as described in product safety documentation.
Q: Can DHS Tar Shampoo be used daily?
The official usage directions suggest an intermittent treatment schedule, recommending the shampoo be used at least twice a week for best results. The labeling also advises that the product should not be used for prolonged periods without a healthcare professional's consultation. This intermittent schedule indicates that the shampoo is not typically intended for daily, continuous use without medical oversight.
Q: Do I need a doctor's prescription to buy DHS Tar Shampoo?
According to the official product information and FDA classification, DHS Tar Shampoo is regulated as an Over-the-Counter (OTC) drug. This means the product is available for purchase without needing a doctor’s prescription.
Q: Is it safe to use DHS Tar Shampoo if I have sensitive skin?
Official safety information indicates that common, localized side effects may include skin or scalp irritation, redness, or stinging. If an individual experiences irritation that develops or worsens, the regulatory guidance requires discontinuation of use. These effects are typical for coal tar preparations.
Q: What should I do if the shampoo gets into my eyes?
The official product warnings state that the shampoo must not get into the eyes. If accidental contact does occur, official instructions indicate that the eyes should be thoroughly rinsed with water.
Q: Why do some people report temporary burning or tingling after using it?
The temporary sensations of burning or tingling are likely related to the product’s irritant effects, which are a documented possibility with coal tar preparations. These dermatological irritant effects are listed as common reactions in official safety documents. These effects are described as common, expected reactions associated with the product.
Q: Can a person with a nut allergy use DHS Tar Shampoo?
The official labeling includes a list of all inactive ingredients in the shampoo (e.g., Purified Water, Triethanolamine Lauryl Sulfate, Lemon fruit oil, Citric Acid). For individuals with specific allergies, the official labeling provides the complete list of inactive ingredients, which a healthcare professional can review.
Q: Why do I need to rinse my scalp very thoroughly after using this product?
The official administration procedure mandates a final, thorough rinse after the second application cycle. This procedural requirement is defined in the official directions to ensure the complete removal of the product from the hair and scalp.
Q: Are there different strengths of DHS Tar Shampoo available?
The specific DHS Tar Shampoo referenced in the official DailyMed records contains 0.5% Coal Tar. The general FDA Monograph allows OTC coal tar products to have concentrations ranging from 0.5% up to 5%, a range broader than this specific product.
Q: Why does DHS Tar Shampoo have a distinct smell?
The product's distinct odor comes primarily from the active ingredient, coal tar, which is a complex hydrocarbon derivative. Some formulations may include additional inactive ingredients, such as lemon fruit oil, which are included alongside the coal tar.
Q: Will the coal tar ingredient stain my towels or shower?
Official labeling and general monograph information indicate that coal tar has the potential to stain clothing, skin, or other surfaces. The labeling advises that contact with fabrics and porous surfaces should be avoided during use and rinsing.
Q: Why is this shampoo recommended for sebaceous gland issues?
Official information describes coal tar as a keratoplastic agent, meaning it works by influencing the growth cycle of skin cells and promoting the shedding of dead skin cells. The regulatory documents describe this mechanism in relation to conditions like psoriasis and dandruff, but do not explicitly detail a link between the product and sebaceous gland regulation.
Q: Is DHS Tar Shampoo meant to replace my regular shampoo completely?
The official directions establish an intermittent treatment schedule, recommending use 'at least twice a week.' The intermittent use described in the official directions suggests it is intended for use as a targeted treatment rather than a complete replacement.
Q: Will DHS Tar Shampoo make my hair feel dry or brittle?
Official safety documents indicate that localized skin irritation and dryness of the scalp are possible common effects of coal tar preparations. While the label does not specifically address changes to hair texture (like brittleness), dryness may be experienced on the scalp due to the product's dermatological effects.
Q: What is the shelf life or expiration date of the shampoo?
Official labeling specifies the required storage conditions, such as maintaining a controlled room temperature, typically between 15 C and 30 C (59 F and 86 F). The specific expiration date for the product is determined by the manufacturer and printed on the container's packaging.
Q: Can I switch back and forth between DHS Tar Shampoo and a non-medicated shampoo?
The administration directions recommend using the product on an intermittent schedule, at least twice a week, establishing it as a targeted treatment rather than a daily regimen.
Q: Does the research suggest tar shampoo is helpful for generalized dry scalp?
According to official indications, the product is intended to help control symptoms of specific conditions that involve flaking and itching: Psoriasis, Seborrheic Dermatitis, and Dandruff. Generalized dry scalp, which is a different condition, is not listed as one of the product’s formal indications.
