folliculitis giver

Although very convenient to use— a few unscented drops a few times a week , it’s caused me far more issues than any good it may have done. There’s an undeniable connection with scalp breakouts/folliculitis the more consistently I use it. I’m giving up. Sadly, I’m out $70 now.

Perfect serum

This serum really helped me recover my scalp. I had some redness and itchiness for a long time and couldn’t resolve it. I tried different shampoos and serums and this one is the one that suits me best. I even noticed that my hair is less greasy than before. Keeping it in my routine further on.

Positive change for scalp health

I’ve suffered from dandruff, scalp eczema and dermatitis for years. The prescription shampoos and treatments from my dermatologist help a bit, but I was always worried how my scalp would recover if the prescriptions removed the “bad” fungus/bacteria but there was no replenishment of “good” bacteria. I’ve only used this probiotic serum for a week and good lord, what a difference- I can’t believe that my scalp itching is almost completely gone, there are fewer flakes, and I’m shocked that my scalp is significantly less oily. I’ve even been able to skip washing my hair for a day (I have had to wash daily my whole life or risk massive itchiness, oiliness, even hair loss and general misery). I’m amazed and I’m so hopeful that this will continue to calm my scalp. I’m absolutely thrilled I gave this a try. Thank you!
