We are going to be doing a very comprehensive hair, skin, and nails formula probably Q1 of next year. It's a very special project to me and it will be more than just a product; not trying to sound vague, it's just a lot to it and will tie in with some special causes and things so there's a lot more to planning it than just the formula, which itself is done.
First, congratulations on the pregnancy. I will keep you and her in my prayers.
The issue with hair loss and pregnancy is that it is usually hormonal but can be from other things. Biotin is one of the standard go to's for that and it does work for a lot of women, but not everyone. The issue and risky part there is that its not safe or ethical for any ingredients to be tested on pregnant women, so there is a lack of knowledge in general on how things will help with that. I do know of a couple of ingredients that may help, but you would need to check with your doctor to make sure it is okay for her to use them - I have seen clinical studies showing that it is, but this is one of those always ask your doctor situations before having her use anything. BUT I want to check and see if I can find a brand of it that I trust or trust more than others for you - do me a favor and send me a pm with your email address, or if you have my email address, send me an email about this. I am making a note to look and see who is making what I'm thinking about right now. I'm actually thinking of doing one when we do a women's line, but that will be next year sometimes.
