Avoid generating an ad with distracting backgrounds or excessive water splashes that may divert attention from the shampoo bottle. Steer clear of lighting that casts shadows or distorts the product's appearance. Refrain from using overly complex or illegible fonts that may hinder readability. Avoid embellishing the shampoo's benefits beyond its actual capabilities. Be cautious with the choice of language, ensuring it is clear and free from potential misinterpretation. Ensure that any additional elements, such as the close-up shot, enhance rather than overshadow the primary image. Avoid making claims that may be challenging to substantiate or may mislead consumers. Be cautious with any artificial enhancements that may misrepresent the actual results of using the shampoo.
