Lamictal and Hair Problems

Oh dear, I get what you mean. I took Lamictal among many other psych meds. I really hope hair is your only issue because I had so many side effects! First of all, there are a ton of mood stabilizers. They all have their side effects, but you can discuss with your doctor switching you to another one like Valproic Acid or Oxcarbazepine. 

I took biotin but it had the unpleasant effect of hair growth on other parts that weren´t my head. But there´s hope! Clean eating, with a lot of healthy fats (nuts, salmon, sunflower seeds, etc) and plenty of fruits and veggies can do wonders. And a good hair care regimen can really help. Avoid washing your hair every day (I know it sounds gross, but it really works) and go for natural, sulfate-free, paraben-free shampoos and conditioners. 

Minoxidil is a great ingredient for hair growth, so you might want to look into a treatment that has it.

I eventually quit psych meds and have been managing my symptoms with therapy and lifestyle changes (mindfulness, yoga, clean eating). It was the best decision for me, but I can´t dare to advise it because I´m not familiar with your story. 

Good luck!

If, you think that Lamictal works for your hair loss prevention that's good you start taking the medicine. If You find the positive results again after using the Lamictal then it's good and continue with it.
