Is Nioxin worth it?

Nioxin works by stimulating hair follicles. To truely get it to work you would need to use the whole line of products, not just the shampoo and conditioner.
Prenatal vitamins work really good on hair and nails.
That said, i actually really like nioxin as a product.

I guess your referring to it helping with the hair loss while you are losing weight. This hair loss is just an acceleration of your natural hair loss cycle (hair that was going to fall out anyway) in response to the stress of surgery, reduced calories, restricted diet, weight loss, etc. It’s temporary. Your new hair is still actually growing but just at it’s usual rate. The hair loss tends to start at around months 3 or 4 & lasts about 3 months +/-. (It seems to be the same length of time for those who take all the hair growth vitamins & supplements like biotin too.) It seems to stop around the time you’re eating more & a broader range of nutrients & you’re not as stressed. It most cases, the only person who really notices the loss is you (& your hairdresser ?).

A lot of us cut our hair if it was long during this time. I did it so it wouldn’t take as long for the new growth to reach the length of my shorter existing hair. Plus shorter hair usually looks thicker, bouncier & healthier.

But you can always try something like Nioxin if you want. Can’t make it worse.

I never tried Nioxin. Personally, time is the only thing that worked for my hair loss. And I tried everything-shampoos, biotin, etc. Don't get discouraged! It is only temporary and it will grow back.

Two things I did to help with hair thinning after my surgery - Shorten it a bit and perhaps add some layers so it reduces the weight. Add some highlights - The color helps thicken the hair a bit. I also have dark hair and a fair scale so it helps with the contrast.

I am doing Nioxin right now because I am way post op and think my current thinning is either post COVID or menopausal.

I had great success with 2 things. Biotin vitamins and vital protein powder in my coffee each day.
