Dr. Berg Scalp & Hair Serum (Improved Formula) with Vitamin D3 & E - Clinically Tested, Paraben- and Sulfate-Free Hair Oil for Women & Men - Includes Rosemary Oil, Castor Oil & Jojoba Oil - 2 Fl oz

I’ve been using Dr. Berg’s Scalp & Hair Serum for about a month now, applying it a few nights a week before bed. The texture is a light oil — not too thick — and it spreads easily when massaged into the scalp. I usually leave it overnight and wash my hair the next morning. After the first week, I noticed my scalp felt a lot less dry and itchy, which was my main reason for trying it. Over time, my hair started feeling softer and looked a bit shinier, especially at the ends. I haven’t seen dramatic new hair growth, but the shedding seems slightly less than before. I also like that it’s made from natural oils like rosemary, jojoba, and castor oil instead of harsh chemicals. A couple of downsides: the scent is pretty strong — herbal and spicy — which some people might love, but it’s noticeable. And if you use too much, it can make your hair look greasy even after washing, so a few drops go a long way. Overall, I’m happy with it. It feels nourishing and has definitely improved my scalp condition. I’ll keep using it to see if it helps with more volume over time. Pros: Softer hair, moisturized scalp, natural ingredients. Cons: Strong scent, a little heavy if overused, results take time.

I’ve only been using Dr. Berg’s Scalp & Hair Serum for a few days, but I’m already seeing noticeable improvements in my hair’s appearance—especially on my crown and temple areas, where I’ve been experiencing hair thinning. Background on My Hair Loss My hair loss started after taking a creatine supplement, which triggered increased DHT levels and led to noticeable shedding. Finding a product that could help counteract this and support regrowth naturally has been a priority for me. Application & Initial Results I’ve been applying the serum twice daily, making sure to massage it into my scalp for better absorption. Here’s what I’ve noticed so far: ✔ Balding areas look fuller already – My crown and temples have shown visible improvement in just a few days, which is surprising for such a short time frame. ✔ Less shedding – I’m noticing fewer hairs coming out when I brush my hair or wash it. ✔ Feels lightweight and non-greasy – Absorbs well without making my scalp feel oily. ✔ Soothing effect on the scalp – No irritation, and my scalp actually feels healthier overall. Ingredient Highlights & Why It Works What I love about this serum is its powerful, clinically tested blend of natural oils that specifically target scalp health and hair regrowth: • Vitamin D3 & E – Helps strengthen hair follicles. • Rosemary Oil – Known for blocking DHT and stimulating hair growth. • Castor Oil – Nourishes and thickens hair. • Jojoba Oil – Balances scalp hydration. Final Thoughts Even though it’s only been a few days, I’m already impressed with the early results. If things keep improving at this rate, I can see this becoming a staple in my hair care routine. If you’re dealing with DHT-related hair loss, thinning areas, or excessive shedding, I highly recommend giving this a shot! ⭐ Rating: 5/5 (So far!) – Will update after continued use!

I don't find the smell a problem. I sorta like it. I used it last night for the first time, my head did not Itch at all the next day. (a good sign) Definitely have to wash your hair the next day, no cheating, it's very oily. But what would you expect? So far I am pretty Happy with the product.

Tiny bottle I use 1 per week but really good product works really well also for scalp allergies

I love this oil. Even my hairdresser says my hair looks better than it has in a long time. I color my gray and I have been doing so for a while, so it get dried out. His oil has helped tremendously.

I literally cannot stand the smell to even use this product. Maybe my nose is too sensitive but it is overwhelming and unusable to me. Can't speak to its effectiveness as I immediately threw it out due to the obnoxious scent.

Smells good! It has a herbal lavender scent that is so relaxing and soothing. I enjoy putting this oil on my hair and scalp in the evening time once or twice a week. I have 4a/3c type curly frizzy hair. It’s very moisturizing and healthy for my scalp and hair. Helps it grow as well. Very soothing to use when my scalp is itchy as well because of the ingredients.

I’ve struggled with a dry, itchy scalp and brittle hair for a while. I already use Nutrafol shampoo/conditioner (which works but is pricey at about $300/year or ~$25/month) and minoxidil foam (Rogaine), which I believe helps with hair regrowth but definitely dries out my scalp. I recently added Dr. Berg’s Scalp & Hair Serum to my routine, and WOW, The very first thing I noticed is that the dryness and itchiness completely disappeared. My scalp feels hydrated and comfortable, which alone makes this product worth buying. I’m now excited to see how this impacts my hair’s strength, brittleness, and regrowth over time. I’m planning to track progress for about 9 months (through June 2026) as a fair test period. If the long-term results match the immediate relief I’ve seen, this serum will become a permanent part of my routine. For now, based on my experience, it’s an easy 5-star BUY.
