It's further promoting the efforts for maximum inclusion by launching a new, first-of-its kind hair pattern search option. The feature of using it will allow Pinterest users to find hair products and ideas based on varying hair types.
Similar to the skin tone search qualifier Pinterest introduced, Pinners will soon also be able to search for ideas specifically based on their hair type. These results will further narrow with even more personalized and useful matches in the app.

As Pinterest reports:

Object detection through computer vision will enable the hair pattern search to help Pinners narrow hair searches down to six different hair patterns: protective, coily, curly, wavy, straight and shaved/bald. In the coming weeks, Pinners can search for a broad hair term such as "summer hairstyles," "glam hair," or "short hair" and then select one of six hair patterns to find hair inspiration relevant to their style and preference.

And there is much to choose from-the system, according to Pinterest, has discovered a hair pattern in over 500 million images thus justifying results based on personal choice.
The filters will be easy to apply, meaning it will be much easier to find more-specific matches for every user-and, as noted, add to Pinterest's broader focus on maximizing inclusion and catering to a broader range of people with functional processes to help guide their discovery process.

And hair, in particular, is an aspect of great interest among Pinners.

"Over the past month alone, there were over 120 million searches for hair and over 5 billion Pins created related to hair on Pinterest. We also saw the majority of the top hair searches on Pinterest are personalized, such as "natural hair twists protective" (15x) and "best haircuts for thick wavy hair" (13x).".

It may not be particularly heavy, practically speaking, but empowering greater inclusivity - at all levels, of course-inherently makes for a great difference for some people and groups, and it is another tremendous step forward, that will surely be followed by other apps.
And from the marketing perspective, that also could inspire more brands to consider the level of representation and inclusion in their Pin listings with users able to hone their results into more specific matches. If you want to maximize your chances, you might also want to ensure you have images that relate.
