Frequently Asked Questions

Like any good wellness routine, results require effort to be maintained. If you stop using GRO Hair Serum, you'll see hair return to its natural state within a few months of discontinuing use.

With GRO Revitalizing Shampoo and Conditioner, GRO Scalp Detoxifying Serum and GRO Dry Shampoo, you’ll see instant results after your first use. When applied daily, expect to see results from GRO Hair Serum in 3-4 months. Results will vary by individual with the GRO Biotin Gummies For Hair. Follow the instructions carefully and you can expect visible results as soon as month 3, with full effect around month 4. Our best advice: Consistency is key.

There is no right or wrong answer. It’s really a personal question and depends on scalp sebum production (oily or dry) and hair density (thick or thin) as well as hair texture.

    Less fall out, thicker feeling hair

    I've been using this for about 2 years and I have to say that my thinning hair feels thicker AND there is not too much fall out in the shower. I do still have some, but it's half of what it was. I highly recommend the serum. I wish it wanted so expensive , though. It makes it difficult to buy at times. (Once in a while I'll get the shampoo and conditioner which is really good. It's gentle and smells terrific.)

    Powerful little bottle

    I've used the hair serum for 2 years now. I was extremely skeptical until a friend told me how it helped her hair growth. Since then, I've used 3 bottles over just my temples where I've always had thinning. Now my hairline has finally filled over the last 2 years with new growth! I have tried countless other DIY methods and commercial products. None have given me the results that this bottle has. But the key is CONSISTENCY. I use it 6 out of 7 days of week after I shower and blow dry my hair. You're not going to see results if you don't use it consistently. Trust me.
