Sheep’s placenta is believed to coat the hair and make it shinier.
Placental shampoo is a type of shampoo that can contain plant or animal products. Manufacturers claim that protein added to shampoo will make hair shinier, but there is no substantial evidence for this claim. Placenta shampoo, although it has seen occasional revivals since the 1980s, is popular mostly in Spanish-speaking countries. Some large retail stores market placental shampoo for the US Hispanic market.
A conditioning shampoo for placenta is ideal for those who have dull and dry hair.
Many people can get sick from reading the word “placenta” on a shampoo bottle. Some people wonder if the human placenta was used to make the shampoo. It is actually sheep placenta that is used in some shampoo brands – it is generally believed that placental protein can help coat hair and make it shinier, which some think also occurs when a woman is pregnant. La Bella is one of the leading manufacturers of shampoos that contain placenta.
Using placenta shampoo can help relieve dry scalp.
Other types of placenta shampoo contain plant extracts. A plant’s placenta is located under the pistil and provides the nutrients from which the fruit develops. Other times, the language on product labels is unclear and it appears that the “placenta” of a plant is any kind of plant essence that will help hair appear thicker and shinier. There is little evidence that animal or plant-based placenta shampoos actually help hair more than any other product intended to add shine to hair, such as oil. Beauty experts who have investigated the chemistry behind many cosmetics say that while placenta shampoo can help, there are many other products that can have the same effect.
The manufacturers of placenta shampoo believe that the protein in the shampoo can be beneficial for the hair.
The use of placentas in cosmetics dates back to the 1940s, when it became a common additive in the then unregulated cosmetics industry. It was used as an additive to cure everything from wrinkles to bad hair. Post-regulation has manufacturers limiting claims to only include that products can add protein to hair.
There has been some concern that placenta-based shampoos could cause cancer. This theory, however, was refuted. Others are concerned with the general “cleanliness” of putting the essence of an animal’s placenta in the hair. Sheep placenta in commercially manufactured shampoos, however, must undergo a rigorous sterilization process before being placed in any product.
