    Scalp treatment using culture supernatant derived from iPS cells is a highly effective method that can directly target hair follicles and the scalp environment, but in order to maximize the effectiveness of the treatment,How you spend your time before and after the treatment is very important.

    "If I'm going to receive cutting-edge treatment, I want it to be truly effective."
    It's perfectly natural to think that way, and in fact, many of the people who come to our clinic share the same feelings and thoughts.
    "Is there anything I should be careful about before and after the procedure?" 
    "Can I go about my normal daily life on the day I receive treatment?"
    "When can I go back to normal shampooing and getting my hair colored at the salon?"
    We often hear concerns and questions like these.

    "I did it without realizing it and ended up reducing the effectiveness..."
    To prevent that from happening, here are some key points that you should keep in mind.

    iPS cellsBefore treatmentNotes

    The latest hair regeneration treatment, which involves directly injecting iPS cell culture supernatant into the scalp, is a very popular treatment at our clinic and has been well-received by many patients.
    However, because this treatment directly targets the scalp, the effectiveness of the treatment can vary depending on how you spend your time before and after the procedure.

    ■ Please refrain from coming to the clinic with styling products in your hair.
    There are no major restrictions on your lifestyle before treatment, so you can continue living as you normally would.
    However,We would appreciate it if you could avoid coming to our clinic with your hair heavily treated with hair styling products such as wax or spray.

    If hair styling products or other contaminants are present on the scalp or hair, these can easily remain on the scalp, and if injections are administered in this state, it not only raises hygiene concerns when inserting the needle, but it may also hinder the smooth penetration of the medication, potentially reducing the effectiveness of the treatment (and thus weakening its effect).
    There's no need to be overly anxious, but ideally, on the day of the treatment, you should avoid applying anything to your scalp or hair other than basic skincare products.

    For those who say, "I have work and I absolutely have to style my hair...", at our clinic, we offer a "Medical Head Spa" as part of the treatment before injection therapy. Our professionals thoroughly remove dirt from deep within the pores and massage the scalp before starting the treatment, so you don't need to be too worried.
    But,For those coming to our clinic for the "injection only" plan, we recommend that you avoid applying styling products as much as possible before your appointment.

    ▼About the treatment process
     

    iPS cellsAfter treatmentNotes

    ■ Shampooing is not allowed on the day of the treatment (washing with warm water is OK).
    • Use of shampoo 
    • The act of rubbing the scalp 
    From the following morning onwards, you can wash your dog gently with shampoo as usual without any problems.
    If you absolutely must wash your hair that night, especially during the summer, and want to feel refreshed, please limit yourself to a simple "water-only wash," where you gently rinse your hair with just warm water without using shampoo lather.

    ■ Avoid scalp massages and applying hair growth products or medications directly to the scalp.
    • Hair growth products 
    • Topical medications 
    • Scalp massage 
    It's easy to overlook, but please take the day off for these activities as well.

    ■ Activities that rapidly increase blood circulation are prohibited (bathing, sauna, drinking alcohol, strenuous exercise)
    On the day of the injection,The following actions that rapidly promote blood circulationWe have asked you to avoid all of these.
    • Taking a bath in a bathtub (please only take a shower on the day of your visit)
    • Sauna, bedrock bath
    • Excessive consumption of alcohol
    • Strenuous exercise that leaves you breathless

    After the procedure, there are tiny wounds on the scalp, so if blood circulation increases due to drinking alcohol, using a sauna, or engaging in strenuous exercise, bleeding may recur from the wounds.
    In fact, there have been cases where patients experienced scalp bleeding due to excessive alcohol consumption on the day of the procedure.
    Furthermore, the scalp is under more stress than you might imagine after the treatment, so overexerting yourself can lead to headaches and general fatigue.
    The restrictions are basically only for the day of the event.Therefore, you can rest well that day and return to your normal routine the following day.

    ■ Wait one week after coloring or perming your hair.
    Many people regularly get their hair dyed for gray hair, fashion colors, or perms, but after receiving an injection,We kindly request that you wait at least about a week before contacting us.
    After the procedure, tiny, invisible scratches remain on the scalp.
    Using strong chemicals such as hair dye or perming solution before a wound has healed can cause severe pain, and the chemicals may enter the wound, potentially leading to scalp problems. Therefore,Please refrain from coloring, perming, or straightening your hair for one week after the treatment.
    On the other hand,There are no restrictions before the procedure.
    It's perfectly fine to come to our clinic for treatment on the same day you've had your hair colored or permed at a hair salon.

    ▼ About the effects of hair dye on the scalp

    Avoid discontinuing medication on your own.

    When people start receiving cutting-edge iPS cell therapy, they sometimes feel like, "I'm invincible now that I'm undergoing this treatment," and they suddenly stop taking the oral or topical medications for AGA that they had been using daily, based on their own judgment.
    However, this is an extremely dangerous act.
    As I've mentioned in previous columns, pharmaceuticals and regenerative medicine have completely different approaches and roles.
    If you stop taking your medication on your own, even though you've been rejuvenating your scalp with regenerative medicine, there's a risk that the hair loss that was being suppressed by the medication will recur, and you won't be able to suppress the attack by the harmful hormones that cause AGA, leading to a rapid progression of hair thinning.

    Each treatment has its own role, and it is not recommended to discontinue it on your own.
    They work best when combined.
    If you are considering reducing or discontinuing your medication, please be sure to consult with a specialist beforehand and proceed gradually.
    Let's make our decision based on that.

    Summary

    iPS cell scalp therapy is a very promising treatment.
    That's why even small changes in awareness or slight differences in how you spend your time can have a big impact on the results.
    However, I would appreciate your consideration.It's a very simple rule: "Only for the day of the treatment (or for one week after the treatment if coloring or perming is required)."
    By strictly following the rules, you can prevent scalp problems and headaches on the day of your treatment, and maximize the effectiveness of the treatment.
    In actual clinical practice, even with the same problem, the underlying causes and backgrounds are truly diverse.
    Because this is cutting-edge medical treatment, let's continue treatment safely and with peace of mind, with the right knowledge.
