Frequently Asked Questions

Is the serum suitable for all hair types?

Yes, it’s safe for all hair types, especially dry, fragile, or thinning hair.

How often should I use it?

Use 2–3 times per week for best results.

Can I apply it to my scalp and hair?

Yes. Use 5–10 drops for scalp care or a few drops on mid-lengths and ends for frizz and split ends.

Should I rinse it out?

For scalp treatments, rinse after at least 1 hour or overnight. For frizz control on ends, it can stay in without rinsing.

How long before I see results?

You may notice a healthier scalp and less shedding within 4–6 weeks, and fuller, shinier hair in 8–12 weeks with regular use.

Will it make my hair oily?

No, it’s lightweight and absorbs well. Use only a few drops to avoid over-application.

Can I use it as a pre-wash?

Most hair oils are primarily cosmetic and coat the surface for temporary shine. This formula combines pure botanical oils with therapeutic essential oils and clinically recognized plant actives, each chosen for a specific biological function rather than just surface-level results.

Is it safe for color-treated hair?

Yes, the natural oils are gentle and safe for color-treated and chemically processed hair.

Scalp & Hair Hydrating and Nourishing Serum

This is the 4th month I have been using the hair serum, 5th month for the shampoo! My scalp & hair feel so clean, my hair soft & smooth, very healthy & shiny! My hair continue to be intact, very little or no shedding at all. I feel my hair is thickening. The bare spot on top of my head seems to be getting thinner, hair growing, though the bare spot is still visible. I am happy with the result from using both the hair shampoo & hair serum by Dr Bernstein. I have recommended your product to my friends.

Scalp & Hair Hydrating and Nourishing Serum

Easy to use. I wash my hair 1-2 times a week, so I’m not sure I ‘ll wake up any hair follicles, but after shampooing, my hair is less limp.

Scalp & Hair Hydrating and Nourishing Serum

I have used the shampoo since 1/16/26, today is 4/12/26, so that is almost 3 months. I also use the serum since 2nd week in February 2026. My scalp feels clean& healthy. My hair feels healthy, smooth, most of all getting thicker & beautiful! The hair loss has stopped right away- when I comb or wash my hair. However, the crown of my hair, I still see some thin spaces but looking better. I see new hair growth on my hairline. Overall, I can see my hair feels thicker & really healthy & glowing!! I follow all your directions. I am very excited about your product- the shampoo & the hair serum! I look forward to reaching my dream! My thick beautiful hair back again with the help of your Tea Tree gentle herbal shampoo by Dr Bernstein & your hair shampoo! I did recommend your product to my friends & neighbor.

"it actually works!! i’m seriously obsessed with the nourishing scalp serum. i’ve been pairing it with the shampoo and my hair has never felt better. after just a few weeks, my hairline looks fuller, my scalp feels clean, and the overall texture is way smoother. It’s lightweight, refreshing, and actually delivers — i’ve already recommended it to my cousin because it’s just that good."

Customer photo review of Scalp & Hair Hydrating and Nourishing Serum

"Less hairfall - will be buying more The brand popped up in my IG feed as I was looking for something that would help with hair loss. After trying out for a few days, I found that there is decreased hair fall when I wash or comb my hair. I then got my cynical husband to try. I diligently put on the serum for him. And, we found a breakthrough. After a few days, he asked me how much the product was because he wanted to buy more. He told me that it actually works. Am glad to find a product that my husband would actually buy and I can use 🤣."

Put it on before bed and my husband literally asked if I got a salon treatment the next morning 😂 Hair is so smooth and shiny now.

Scalp & Hair Hydrating and Nourishing Serum

Bleached my hair too many times and it was a mess. This has seriously helped repair it. Feels stronger and looks way less damaged.
