Review: It works, if you use it for the right condition and with other meds - This worked for my boyfriend - he had bald spots all over his head from alopecia areata. After a few months of using this product as well as the shampoo and conditioner, all his hair grew back. It's hard to say if this is the reason why it grew back (he was also applying a cream), but it seemed that using this product was the turning point for his condition. It will not work for everyone, as it will likely only help for alopecia areata involving a lack of thymus hormone. Studies on alopecia areata show about 3/4 of people with the condition have a low thymus hormone level. However, alopecia areata is complicated and that's often not the only reason the hair falls out - so the only way to know if it works is to try it. Expect to have to purchase it twice, as it needs to be continued for a few months. Ultimately the course of treatment will run you about $500-600 as of this review, since you really should buy all 3 twice: serum, shampoo, conditioner. Not that much considering the alternative is losing your hair in unsightly patches. But most doctors recommend using multiple treatments. You should also visit a dermatologist and get prescription medication/injections/cream depending on what they recommend. I would imagine the chance of success by using this alone is not as good, since low thymus hormone is not the only reason the hair falls out.

### ⭐ Made my Hairline Recede a bit... Very Disappointed...
*by J***N on July 19, 2025*

Not sure if I got a Bad Batch of this Thymuskin Gel or what, but it actually caused my hairline to recede quite a bit, almost half and inch Backwards. Not sure, why, but it's Definitely from the Gel. I actually like and use the Thymuskin shampoo still, so, it shouldn't be that. I used to use the old version of the Thymuskin Gel (back when it was sold in a glass bottle) :) And I Honestly LOVED IT back in the early 2000's. Not sure what all happened here... But, I was REALLY shocked and disappointed with the results of using the new Thymuskin Gel... Sometimes, Newer isn't always Better... Very Disappointed Buyer, Here... 😢😢😢😭😭😭🙏🙏🙏
