It’s hard to say who the best natural hair youtube channel belongs to. There are literally hundreds of women who are natural youtubers and they all have hair journeys worth following and listening to. It all comes down to whether you want to start at the beginning and grow with that person or jump right into being a watcher of veterans who have been around for a couple of years.
The difference will be thousands of subscribers and probably better video quality with the vets. The downside is your questions may not get answered right away if at all. You will probably see ads being ran on their videos and the message may change due to sponsorship. Everybody has agendas and integrity levels that differ so you will have to decide for yourself. I hope this helps as you begin to engage the content of video bloggers of vloggers.
